Sony Vaio VGN-UX50 uPC review


Ultra portable PCs (uPC) seem to be really hot right now. With Microsoft’s Ultra Mobile PC (UMPC) / Origami devices being announced here there and everywhere, it looks like this product category has the potential to become as popular as PDAs were a few years ago.

Maybe… Exactly one year ago I reviewed the Sony Vaio VGN-U71P ultra portable Windows XP PC. Despite a few minor complaints, that little guy made a very good travel companion. To this day I kick myself for deciding to get rid of it… Especially now that I don’t have even one Windows PC in the house any longer. Yes, Mac person here.

I was more than a little excited when I learned that Sony had decided to announce a new uPC a couple months ago. Not content to jump on the Origami bandwagon, Sony has come out with their own ‘everything but the kitchen sink’ style device. The UX series Personal Computers as Sony calls them, are available in 3 different models: the UX50, UX90S and UX180P. The UX50 and UX90S are both Japanese models that are currently available. The UX180P will be the US version that should be released sometime in July. The differences between the different models are as follows… The UX50 has a 1.06GHz processor, while the UX90S has a 1.2GHz processor. The US version (UX180P) will have a 1.2GHz processor, XP Pro instead of XP Home, and a Cingular EDGE modem instead of a CompactFlash slot.

Our friends at Dynamism were kind enough to let us borrow a UX50 for a brief period to review. When I say brief, I really mean brief. I received the package around 6pm on a Thursday evening and had to ship it back the following Monday. As you can imagine, this review will not be our standard 2 week usage review. It will be more of a first impressions type of article. With that said, let’s get on with the show!

My first impressions of this device were that the pictures that I had seen on the web, did not accurately convey just how thick and heavy this little guy was. I’m not sure even my pictures here can get that point across. The UX50 isn’t a pocket device by any means. It’s still gear bag sized uPC that just happens to have a PDA sized display.

The UX50 is designed so that you can hold it between your hands while you use it. The back side has hand grips similar to those of the Sony Play Station Portable handheld gaming system. One of the grips actually
houses the rechargeable battery pack.

Unlike other Origami devices currently on the market or recently announced, the UX50 has a built-in QWERTY keyboard. It’s revealed when you slide the display up. Anyone else thinking of the OQO? It appears that Sony borrowed that design for this feature.

Sliding the display upwards will bring the computer out of standby. It will also allow you access to one of the built-in cameras.
A 306k pixel camera is located on the face in the top middle of the display frame.

The other camera is 1.3 megapixels and is built into the back of the display. You can see it in the top left corner of the picture above.

Two cameras give this computer the ability to do video-conferencing and mobile blogging / video capture.

Click thumbnails to see unaltered snaps.

The digital picture quality of this device leaves a lot to be desired though. The 1.3mp camera does an ‘ok’ job with macro shots (there is a macro and normal shot switch on the top of the display), but normal shots are pretty blurry. There’s also the fact that it’s close to impossible to use the camera outside in bright sunlight. Why? Because the viewfinder is the computer display, and it totally blacks out in direct sun.

The stylus silo is also located on the back of the device. It is built into the top right corner of the battery compartment grip. The stylus is your typical telescoping PDA style stylus. Nothing fancy.

Along the top edge of the UX50 is a set of heat dissipation slots, a Memory Stick Duo slot and a camera capture button. The shiny black tubular looking appendage running along the bottom edge is the WiFi antenna.

On the opposite end, you will find the AC adapter port, docking connector, earphone jack and microphone jack, along with more heat dissipation slots. The bottom edge of the display has several status LEDs that show battery charging status, hard drive access, Bluetooth and WiFi radio status.

The left side of the UX50 has a Compact Flash memory slot. According to Dynamism’s site, the US version of this uPC, will not have a CF card slot. Instead, it will have a Cingular Edge wireless modem built into it.
That’s a shame since the CF slot makes this device very handy for offloading digital camera pictures. There is also a full sized USB port located on this side of the device.

On either side of the display there are several thumb accessible buttons. On the right side, you’ll find (from the bottom up) the Power / Hold switch and Power status LED. Slide this spring loaded switch upwards to power on the device or put it in standby mode if it is already powered on. Slide it down to put it in hold mode. When powered on, the status LED will glow Green, and while in standby mode, it will slowly flash Amber.

Above the Power switch are the zoom buttons. These change the magnification of the display. At the very top is the thumb mouse stick. This is a hard rubber pad with a rough surface. This surface allows you to easy move the onscreen cursor around the screen without your thumb slipping off. You can also tap / double tap this mouse stick to select or launch applications.

An easier way to select and launch applications is to use the two buttons located on the other side of the display. The top button reacts like a left mouse button, and the button directly below it acts like the right mouse button. Using these buttons with the mouse stick makes navigating screens, web-pages, etc. easy and comfortable.

Also located on the left side is the special Vaio launcher application button and Wireless on/off switch. The wireless switch will power on/off both the Bluetooth and WiFi radios.

The built-in keyboard on the UX50 sure isn’t the most user friendly keyboard I’ve ever had the opportunity to use. It is a welcome addition, don’t get me wrong. But the keys are quite small and almost completely flush with the case. This makes it very difficult to thumb type without looking at the keys to make sure your thumbs are pressing the correct letters. The keyboard has 64 keys with a 0.15mm stroke and 8.6mm pitch. The keys do have good tactile feedback and are backlit in blue.

For real typing though, it’s best to use the included docking station / port replicator. When connected, the UX50 is at a perfect viewing angle and using the built in USB ports (there are 3 on the port replicator, and 1 on the UX50), you can connect a keyboard and mouse for added working comfort. It is also possible to use a Bluetooth mouse and keyboard with this computer.

There is an iLink connector (aka FireWire), video out and Ethernet ports on the back of the replicator. With this setup, you can use the UX50 like a regular desktop computer and then when you want to go on the road, you can just unplug the computer and go. Leaving all the cables connected and undisturbed.

For added convenience, a smaller video out, Ethernet jack dongle is also included. Bring this with you when you travel.

The UX50 has a feature that I’ve not seen mentioned for any other UMPC / Origami devices yet; a fingerprint scanner.

The scanner is located in the top left corner of the display. It look me quite a while to figure out how to activate it. I finally realized that there was an application icon in the task tray that controlled it. First you have to password protect your user ID with a regular text password. Then the software will guide you through the process of swiping and enrolling your fingerprints as passwords.

Following the steps is a simple procedure. I had no problems recording my fingerprints or completing the enrollment process.

You don’t have to scan each finger during the enrollment. I actually just scanned my 2 index fingers and that was all. Once you finish the procedure, every time you restart your computer or come out of standby mode, you’ll be presented with the regular Win XP login screen. Instead of typing a password, you can just
swipe your finger. It’s really fast and easy and I never had a problem with it recognizing my finger swipes.

Now let’s talk a little about the overall size and construction of the UX50. As you can see in the pictures below, it’s not a whole heck of a lot bigger than my Treo 650!

When closed, the size is very nice for travel (as long as you don’t also need to carry the port replicator, AC adapter, an external mouse and keyboard along with it). It’s bigger (thicker) than the OQO, which does make it feel a bit bulk. That said, almost everything else about the UX50 is better than the OQO. Mainly the screen is brighter, not so horribly spongy, and is accurately calibrated for touch screen usage.

Again, in hand, this device feels heavy and thick. But at 1.5 pounds, it’s smaller and lighter than almost any regular to smaller sized notebook on the market. So you have to take the good with the bad.

As far as build quality with this device, I would say that the UX50 is a solid little uPC. I wouldn’t want to drop it on a hard surface, but it feels rugged enough to withstand regular everyday use. It is solid and didn’t
yield any creaks or groans when I performed the requisite Gadgeteer squeeze test.

Battery life for this little guy is supposed to approach 4.5hrs. I don’t know how accurate that is though. Maybe if you turn off the backlight and don’t access the hard drive. By default, the battery life indicator on my review until reported 2hrs after a full recharge. That was on the optimized setting. This is where I have a real gripe about all uPCs. That’s just not enough untethered power for a device that is supposed to be totally mobile. Who wants to carry around an AC adapter and power cord with them everywhere they go? Not I.

Besides Windows XP Home, the UX50 doesn’t come loaded with any super fantastico software bundles. It does come with SonicStage, Sony’s iTunes like store front for purchasing music.

There’s also a simple application launcher that is activated when you press the button on the left side of the display.

The launcher interface isn’t fancy, but it is a quick way to change volume, brightness etc There’s also a button that you can tap to rotate the screen 90 degrees. It’s also where you can launch the little handwriting application.

The handwriting app seemed to be for drawing and not writing, like I thought it would be. I assumed that it would allow me to use HWR (handwriting recognition) to fill in fields or write lists. As far as I could tell (all the dialog boxes are in Japanese), it is just for drawing on the screen. Hmmmmm….

That brings me to a big grumble… Why doesn’t this device ship with the tablet edition of Windows XP? The UX50 is a device that is perfectly made for that version of the OS… I don’t get it.

Back to the screen / display. Like most Sony devices, their displays are very nice. Bright, vibrant, etc. But there is a problem with the UX50 display… It’s too darn small! It’s just 4.5″ diagonal. For a PDA, it’s a perfect size. But for Windows XP, it’s pretty hard to read text. By default, the screen resolution is set to 1024 x 600. You can set it to something lower, but it doesn’t help all that much because then you can’t fit as much info on the display. The Zoom buttons aren’t very useful either as they just pump up the size (a maximum of 3x) and allow you to scroll around on the screen. It doesn’t allow interactivity with the running apps. It’s just a view only zoom.

The thing is that small screen sizes haven’t been that much of an issue for me until this device. I have not had any problems with my Treo 650 and had no real problems with the Sony Vaio VGN-U71P either. Maybe it’s because I’m close to needing bifocals. Or maybe it’s just because everything on the UX50 has been crammed into an itty bitty 4.5 inch display ;o) For viewing images, it’s not a problem. The only problem is with reading lots of text. I find myself squinting quite a bit.

Even though I love the idea of an ultra miniature PC, it comes down to the fact that these devices just don’t give me quite what I need in a mobile device of this size. First of all, the screen is too small for true Windows XP use. Maybe it’s just me and my eyes though. Then there’s the battery life issue. When will our mobile devices be able to get us through an entire 8hr work day without needing to be recharged?

With all that said, I still think the UX50 would make a great travel companion for someone that doesn’t want to lug a full-sized laptop with them on a trip. Using this device for picture offloading, websurfing and emailing would be perfect. Hardcore photoshop work, spreadsheet work, powerpoint presentation creations, etc, might present a problem. Unless you have bionic eyes or something ;o) I don’t want to be too hard on Sony, because they seem to be the one of the few companies that continue to push the envelope and bring innovative feature rich products to the market for us consumers to drool over.

    Judie received this email from one of our readers, that might be useful to someone considering the UX180:

    I am a long time fan of your site (fabulous) and was reading your 6/8 post and why you decided against the Sony UX 180 because of the Cingular service. I am an IT manager and support many Sony laptops with the built-in EDGE modem. (I am typing on one now.) The first thing I do when I get one of these is unlock the modem and put in a T Mobile SIM card with data service. You could use any GSM data service provider at that point and you would not need to get the Enfora or any other add-on devices.

    One thing to keep in mind though is that if you intend to use this in California with T Mobile service, coverage can be a little spotty in some parts of the state. I get gripes from my consultant that has clients in the San Francisco Bay area regarding the T Mobile coverage there.

    The following link is to the Sony KB and details the process:

    Strange…I was drooling over the OQO…until I actually got my hands on one…but this Sony offering has left me cold from the get-go. I guess I am still hopelessly waiting for the darned Vulcan Flipstart…

  • MeanSquare June 15, 2006, 2:28 am

    On the whole, I think it was a fairly good review, hampered perhaps by the short time you had to review the unit. I think the UX might have grown on you with a few days use, but I can’t say for sure it would. You did say “Even though I love the idea of an ultra miniature PC, it comes down to the fact that these devices just don’t give me quite what I need in a mobile device of this size.”

    In some ways, handtops are still a bit ahead of their time. The OS is still designed around larger desktop/laptop displays (although that can largely be overcome by resizing the fonts) and, as you stated, battery life is not all it could be (although Sony power management would get you closer to the 4.5 hours possible from the standard battery). In their current state, they certainly aren’t for everyone.

    If you don’t need the power and transparent desktop compatibility, then a PDA will suffice much better. If you need more power and size isn’t as much of a consideration, a laptop is a better choice. For those of us who need or want full OS capabilities in a mobile device that we can take just about anywhere with us, the UX is the current item of choice.

    Thanx for the review. Like you, I’m a Mac and Palm user and find it weird not having a Windows box around. I’m interested in the UMPC-like Windows machine as they don’t take up much space and I can have Windows on those extremely rare occasions when I need it.

    I like your review of the UX50 and wish you’d had it a while longer so that you could tell us how you balance it with the Mac and Palm in everyday use.

    Will you guys be reviewing the Samsung Q1?

    For now I’ll wait for;
    1. The UMPC prices to reach $500 or thereby – can’t pay much more for a Windows machine and I don’t want a cheap large Windows box in my office.
    2. Aple to release an UMPC. There’re all indications they’ll do so.
    Fingers crossed.

    By the way, I’m glad you and Judie took 2 different paths – Mac/Palm & Win/Pocket PC. Makes for excellent product coverage. Was that intentional?


  • Julie June 15, 2006, 11:48 am


    I’d very much like to review one of the new UMPCs. I might ask Dynamism. I believe that they have the Samsung in stock. I wonder how it compares to the Sony.

    Regarding my choice of running Mac and Palm, it was not intentional… I have been back and forth with Macs for a couple years now. It’s just now ‘stuck’. As for Palm, I have always found that platform to be easier to use and overall faster. Windows Mobile still seems sluggish and cumbersome to me.

  • strider_mt2k June 15, 2006, 4:48 pm

    Nice review, and a slick looking unit to be sure.

    I simply don’t trust Sony above the level of a 20-dollar set of headphones anymore.
    I’ll bet I’m not the only one that feels that way either.

  • clingeek June 15, 2006, 10:40 pm

    Hi Julie. Great review. Matt Miller (palmsolo) has posted a great review of the Samsung Q1 on ZDNet. Here is the link:

    He really seemed to push it to the limits on a business trip, which is why one would buy a UMPC. The base price is reasonable and even with add-ons (BT keyboard, 1GB flash, etc.) you’re still in the range of a mid-range (but heavier) laptop.

    Best regards, Dave R.

    Good review Julie… Thanks for the info.

  • lorint June 18, 2006, 4:50 pm

    I’ve been using mine for two weeks now, and love it. Picked up a UX50 in Japan at Yodobashi camera. I’m getting a bit faster at the thumb typing, but never expect to be better than about 30wpm. For those that don’t like the small screen so much, try changing the font size in the Display icon in Control Panel. For me the default is not bad since I have fairly good eyes and crave all the real estate.

    Here’s an unboxing / first impressions video from when I got the machine:

  • NakMan July 5, 2006, 8:00 pm

    I got mine (a UX180P) on Monday, and have been installing a lot of software and transferring data from my U750P over.

    My comments are from the perspective of a U750P user, which I was very happy with and carried with me where ever I went.

    The screen is smaller, but much sharper due to the smaller pixels. Going back to my ‘750P, the ‘750P almost looks blurry by comparison. This is a very bright gorgeous screen, with excellent digitizer like on the ‘750P.

    The thumbboard is a very useful addition, and I have no problem with tactile feedback. It’s nice to be able to slide up the display and type in a password or URL or whatever instead of having to write it onscreen (using RitePen, which works very well, BTW) or get out the ThinkOutside BT keyboard. For anything other than a quick E-mail message, only a fullsize keyboard will do but this is an acceptable solution to the problem of making the entire unit large to accomodate the keyboard.

    The unit is much easier to hold due to the shape of the back. The ‘750P had a flat back and I much prefer the “grips” on the ‘180P. The unit is much lighter than the ‘750P (with standard battery).

    The pointer stick is much more sensitive than that on the ‘750P. I’ll have to play around with the settings as I got used to tapping on the stick to do a left mouse button click and this doesn’t always work on the ‘180P.

    I signed up for the 30 day free trial of Cingular WWAN service (I’m a Sprint phone customer who uses his phone as a wireless modem via USB cable connected to the U750P). This works reasonably well, but isn’t the fastest. My Sprint data connection through my phone is much faster but is much less convenient as I have to get out the cable and have a surface available to set the phone on.

    WLAN performance is great, but I have to admit that at home and work I am close to an AP so I’m not stressing it at all as far as signal strength.

    The Bluetooth is very nice to finally have integrated in the unit. On the ‘750P, I used a Socket Communications CF BT card. The builtin BT on the ‘180P paired with my ThinkOutside keyboard and mouse, and also my Delorme BT GPS receiver. Contrary to my initial attempts, I was very happy to find that it <u>would </u>pair with my Logitech BT headphones. I just have to use the Toshiba BT control applet to connect to the headphones, and Winamp output goes out over BT to the headphones. No more BT dongle!

    The zoom feature is very nice, and despite the pixelation that can result at certain magnification settings, it does what it’s supposed to do – allow you to easily read the sometimes very small fonts in apps.

    I don’t have much use for the cameras, but they’re there if I need them, I guess.

    The fingerprint reader is another great feature for a uPC as it eliminates the need to type in a password (via onscreen keyboard for the ‘750P) to login. Since this was a problem on the ‘750P, I just didn’t even use a password.

    The unit seems more sluggish than the ‘750P but this may be due to the fact that I haven’t finished eliminating all the unneeded software running on it.

    I was used to 1.5 to 2.5 hours of battery life from the ‘750P, so the similar performance that I’m seeing with the ‘180P is not too disappointing to me.

    All in all, this is a worthy replacement for the ‘750P, which I really liked. I can’t see using a PDA ever again especially if manufacturers develop technologies to implement instant on/off on these uPCs and improve battery life, of course. Being able to read and compose E-mail, surf the web, and paly a game or two almost anywhere is a great convergence of technology.

    Do you plan on reviewing the UX180P? Either one of you going to buy one? I’m saving for one now.

  • Julie August 11, 2006, 7:22 pm


    I don’t have any plans at the moment to review the UX180P. I think this review pretty much covers the major hardware topics. Although I enjoyed the UX50, I didn’t enjoy it enough to buy one of my own 🙂

  • Chris January 12, 2015, 5:18 am

    Hi Julie.
    I know its now 9 years after you wrote this review but thought it would be fun to comment.
    I had a Vaio UX when they first became available in the UK (2006/7), I used it for a while (IT Manager) but then the novelty wore off and it became a paper weight docked on my desk, this was mainly due to the screen size, even with perfect eye sight it was still a struggle to see the small text and click on the tiny buttons in text boxes ect……one thing though, you state in the review that the zoom function is only a viewer, this is actually not true, when you press one of the zoom buttons a dialogue bar opens allowing you to increase or decrease the zoom level, at the top of the dialogue bar there are two icons, a hand and a pointer, if you click on the pointer you can then interact with the zoomed desktop as normal, as you near the edge of the screen it automatically pans in what ever directions you are moving the mouse pointer to allow you to see the part of the desktop that is off screen, it defaults to view only mode. This makes the world of a difference when using the UX fully mobile, well in actual fact it makes it usable to be honest, but this is still a right faff having to zoom in click on something then zoom out to view the result then zoom in click on something and so on…..but if I had a server have an issue that was service affecting it was a god send to quickly whip out the UX, dial in and remotely control a server to fix the issue without having to lug a full laptop around.

    Well now its 9 years later, tablets of all varieties have invaded the mobile computing space, mobile phones are now mini tablets so mobile computing is fully covered with usable screen sizes and enough horse power to cover all eventualities, but you know what, I still have my trusty UX (UX1XN), now running windows 8.1 and I have to say that i’m amazed at how well it runs considering the age gap between the hardware and the OS, it runs everything perfectly, all buttons work and the metro front end is perfect for small displays, I have a plethora of tablets and notebook / laptops that I can lay my hands on but at the end of the day I still take the UX, its been with me for all these years, hasn’t missed a beat and is still usable for light email and web surfing, we’ve covered some miles together and supported and maintained some of the largest networks in the world, it still draws curious and admiring glances when I’m having a coffee in a coffee shop with it standing on the table, IT folk just give an approving nod and smile, where as normal folk frown as if to say “What is that?”.

    I think this is testament to Sony’s design and engineering but was probably too early to market by some years to take a hold of the niche market that the umpc’s market is.

    All the best, Chris
