Palm Zire Review


Product Requirements:
PC running Windows 98/2000/ME and XP
(2000, and XP require admin rights to install) or
Mac OS 9.x and Mac OS X v10.1.2 or higher

Just like PCs, PDAs are also available in high end models, and low end models.
The high end models are typically geared toward power users and people with deep
pockets, while the low end models are marketed to the beginner or budget
conscience consumer.

Palm’s low end model has been the m100 series. The m100 was the first sub $150 Palm OS PDA on the market. The m105 has since taken its place as the entry level PDA. How does the Zire compare to the m105? Is it the better choice? Let’s find out.

Hardware Specifications:

Processor: Motorola Dragonball EZ 16MHz Processor
Operating System: Palm OS software v4.1
Memory: 2MB of memory
Display: Monochrome, 160×160 Pixel
Interface: HotSync Cable Standard Mini USB, Infrared
Power: AC Adapter 120VAC, 60Hz
Battery: Rechargeable lithium-ion battery
Dimensions and Weight: 4.4 x 2.9 x 0.6 in. / 3.8 oz.

Arriving in a sealed plastic retail display type container, my first
impression of the Zire was one of annoyance and waste. Annoyance because the plastic packaging is a freaking pain to get open without a knife, scissors or abnormally sharp teeth. Waste because the container will not be accepted by most recycling centers… or at least the one I frequent. I’ll hop on a soap box for a second and say that I feel this type of packaging is irresponsible. We
don’t need more crap like this clogging up our landfills… Ok, I’m hopping off
the soap box now.

Once I actually got my hands on the Zire (also known as the m150), I was
pleasantly surprised by its size and feel. I guess I was thinking that it was
going to feel as cheap as its price tag. On the contrary, it is a very solid little
PDA. It passed my squeeze and creak tests with flying colors. Even shaking it
yielded no rattles.

It has a nice weight and feels comfortable to hold and use. Size-wise, it’s very
similar to the Sony CLIÉ T series. The perfect shirt pocket size.

Is it just me, or does the Zire look vaguely familiar? The iPOD springs to
mind every time I see its white ‘face’! I’m curious to see if Palm will sell Zires in
other colors in the future. Unlike the m100, 105 and 125, the face plate on the
Zire is not removable. The front is a very shiny white plastic that almost looks
like enameled metal. The back is a slightly sparkly silver / grey. Style-wise, I
it more attractive than the m100, 105 and 125. I never really liked the
bulbous look of those models.

The Zire’s display is almost identical in size to the m100, 105 and 125. It is a mono display and does not have a backlight. Even so, the display is sharp and easy to read in most lighting conditions. I did notice some slight streaking when testing some games.

The screen is very smooth and is easy to write on with a stylus. It is
slightly spongy though… but this is only something that you notice if you hold
the PDA at an angle as you press down with the stylus.

Below the display are 5 buttons. A small power button, 2 application buttons
and the up / down scroll buttons. All of the buttons sit flush with the case,
can not easily be activated by accident, and have excellent tactile feedback.
Instead of having 4 application buttons, the Zire has only 2. The left button is
the Date book, and the right button is the Address book. Both buttons are large
enough so that pressing them is a simple task. The scroll buttons are also a nice size.
Pressing the Up scroll when the Zire is powered off, will power it on and show
the clock application for 5 seconds before powering back off again.

The top of the Zire has the IR port, AC adapter connector, Hotsync port and
stylus silo.

I found the IR strength to be really good. I was able to beam addresses to
and from a Tungsten T at a max distance of 5 ft.

Instead of having one connector for both charging and syncing, there are two
seperate connectors.
A cradle isn’t included with the PDA, so you plug the AC adapter directly into
the Zire to charge the batteries. The AC adapter is very small unlike the AC adapter that Palm uses for their other models. To sync the Zire, you use the included USB
cable. One end plugs into a free USB port on your PC or Mac, while the other end
plugs directly into a small connector at the top of the Zire. That’s right, this device does not have the universal connector. This means that you won’t be able to use any of the current
Palm peripherals such as the Stowaway keyboard. Also important to note is the
fact that the hotsync cable does not have a button to initiate a sync. Instead
you have to turn on the Zire, navigate to the hotsync app, and tap the button on
the screen. I should also point out that the Zire does not have any status LEDs
to let you know when the PDA is charging (by the way, the green stripe on the
power button is NOT an LED).

No surprises regarding the stylus. It’s an all plastic stick that doesn’t
have a hidden reset pin. Speaking of resetting the Zire, the switch is on the
back of the PDA. Also on the back is a horizontal slot that is the attachment
point for the included rubber screen cover. The screen cover is a blue flexible cover that
can be easily attached and removed from the PDA.

Performance-wise, the Zire is not going to win any races. By today’s standards, the 16mhz Dragonball processor is pretty long in the tooth. It is actually the same one used in the 2yr old m100
and the m105. It
performs just fine for PIM tasks, but struggles when running large applications such as Quickoffice or when trying to play newer games. If your main intent for the Zire is for basic PDA functions and nothing too fancy, it will serve you just fine. Anything more intense, and you’ll probably not be happy with it.

The software side of things is pretty sparse. The Zire comes loaded with the following applications in ROM:

Address Book
Date Book
To Do List
Memo Pad
Note Pad

As you can see, there isn’t a Mail application included. You’ll need to use a
3rd party’s app if you wish to sync your desktop email to the Zire.

Also included on CD, is the Palm Desktop software for Windows and Mac, and PocketMirror® by Chapura®, which allows you to synchronizes the Zire with Microsoft Outlook (Windows only).

The only bonus software titles included are: Mine Hunt, Puzzle, Giraffe, and Hardball. Oh boy!

One nice addition is a certificate for 6 months free lost and found service from

On it’s own, the Zire is a nice PDA. It is small, sturdy and inexpensive. It would make a great PDA for a student or someone that has never had a PDA before and would like to test the waters
for usability. The only problem that I have with the Zire is the price. I think it should actually be about $20 – $25 cheaper. The reason why I say this, is because currently Palm is selling the m105 for the exact same price of $99. The m105 has more memory (8mb
vs. 2mb), a backlight, interchangeable face plates, and a variety of available cases, styli, keyboards etc. What it doesn’t have is USB syncing (it comes with a serial cradle),
rechargeable batteries (it uses 2 AAA’s) and OS version 4.1 (it has v3.5).

If you are only looking for a PIM (Personal Information Manager), do not have any intentions
or need to interface with other peripherals, and want the newest and smallest
budget PDA, this is the one to take a closer look at. If you are even remotely
interested in installing lots of 3rd party applications, or doing anything more
than using the PDA as a date book and address book, then I would advise you to
buy the m105 or to save an additional $50 to buy the m125. It has 8mb of RAM, an
SD slot and the universal connector.

    This is pretty cool. Very expensive though. Makes me wonder how good of quality MPEG4 is, though.

    I had one of the older models for a brief time. It was a fun little unit that created surprisingly crisp movies. I’d really like to get a digital camcorder sometime soon… Maybe I should splurge on this one? 🙂

    My Palm Zire m15o has been serving me well for many years. However, l’m suddenly unable to synchronize addresses from the computer to the palm. What am I doing or not doing that has caused this to happen? I’ve never had a problem before. Can anyone help?

  • Lo December 4, 2009, 10:15 am

    I just dug up my old Zire m150 and it still works. I find it interesting to note that you can actually charge the m150 with the USB connection as well. It takes a little longer than using the other charger, but it does work fine.

  • Collette December 11, 2009, 5:37 pm

    I had a Zire M150 in the USA and took it to Europe. I didn’t charge it on time and it went dead. A store told me it has to be returned to the USA factory to have it reset. Has anyone else ever had this problem or have any tips? Thanks.

    I have an m150 palm zire that I bought off of Ebay for 6 dollars a few months ago. The seller had taken extreme care of it as it moves without a hitch. My only problem is the 2mb memory. So tonight I bid on the palm zire 21 with the 8mb. I put in 2 bids and won the item for 21 dollars, altho I had bid 30. I had bought a color palm that would not calibrate, so its useless except for time date and addresses. I also bought a Dell axim that won’t work well with memory cards. I figure its like my dad use to say before he died. You can even buy brand new cars that prove to be worse then the one you had. I’ll stick with the palm m150 with the 2mb until the other one arrives. Maybe, just maybe, I don’t need to know to much anyway!!!!

    My zire wont turn on or do any thing even when plugged in dont have charger, but do have usb cable??? Any suggestions????

    • Julie December 27, 2009, 10:00 pm

      @Chad You need the AC adapter to charge the battery. The USB cable is only for syncing to your computer, not charging.

  • Mike January 11, 2010, 4:21 am

    @Julie – No, you can charge it from the USB cable as long as the port is USB 2.0 compliant. Almost every computer made in the last 5 years is USB 2.0 compliant so it should work unless the battery is worn out.

    @Collette – No, you don’t have to send it in to the factory if all that’s the matter is a discharged battery. Charge it, sync it, and you’re ready to go.

    me ajudem, estou tentando sincronizar meu zire m150 mas está me parecendo impossivel com o cd original, o que devo fazer para que sincronize perfeitamente

  • Pat April 21, 2010, 10:34 pm

    My trusty Zire appears to be suffering from old age. Like older people, it has a lot of information stored in its memory that I can’t bear to lose.

    I put a new appointment in my Zire the other day and hours later, I found it was still on. I tried to turn it off and was unable to do so. Rather than keep it on until the battery died, I put it on “life support” — the charger, until I could figure out how to revive it, if possible. Any ideas?


  • Lisa May 15, 2010, 10:52 pm

    I bought a used Zire m150 today and I charged it, but can’t get it to work. The touchscreen is unresponsive and I have tried resetting it several times. Anyone know what I can do to fix the touchscreen? It comes up for calibration in the top left of the screen, but a touch anywhere on the screen still does not work! I kinda wish I didn’t buy it! Please help!

    • Julie May 15, 2010, 11:17 pm

      @Lisa Unfortunately it sounds like you may have purchased a dud 🙁 does the touch screen work at all? Can you return it?

  • lisa m June 26, 2010, 2:32 pm

    i have the zire m150 and it just quit on me – i have some power but it shows all my data is gone – i use it all the time but left it in the the trunk of my car in the heat and now it seems i lost everything – already tried resetting with no luck – any ideas?

    • Julie June 26, 2010, 4:37 pm

      @Lisa you should still have all your data on the computer that you sync it to. You could find a used (working) one on eBay, plug it in, sync and there’s all your info.

  • James December 13, 2010, 10:46 am

    I have lost the charger for my m150 and wanted to know what size to buy at like radio shack?

  • Kameswar December 27, 2010, 7:53 am

  • Brenda January 1, 2012, 12:13 pm

    I have a Zire M150 and now have a Mac and the software that I had is out of date and need to find an update software so I can add it to my mac computer so I can use the Zire, I love it.
