For your iMac, I'd use the Apple keyboard, it matches the white iMac quite well, and is a nice keyboard to begin with.

I think this keyboard would be great for anyone that has ordered one of the new iMacs with the Aluminum finish.

I really don't understand what Apple was thinking when they redesigned the keyboard. (and especially the wireless one)

I'm in complete opposition to Tylers view, however Apple hasn't given anyone the choice. It's the new keyboard or an aftermarket one. And I like the old keyboard, which isn't available anymore.

There are many other products out there, one of them is the Sony GPS-CS1 and it is a decent little unit. One of the bigger faults I see with the ATP unit is that it takes a reading every 5 minutes.... as you found, there are definitely inaccuracies with that method. The Sony takes it continuously, every second or so.

The Sony is also a completely different animal, it is basically a USB drive that writes it's own files to the drive. When you get back to the computer, you plug the Sony in, and run some software that applies the time stamp to the file.

There is some drawbacks though, Sony only ship software for Windows with the unit. If you have an Intel Mac and are running Tiger, you're fine. It doesn't work if you have a PPC and running Tiger. Apple seems to have fixed this problem with Leopard though, and now neither Intel or PPC will work. So mine is sitting in my camera bag, useless.

Also on the Mac, I use a a program called HoudahGeo for my geotagging, I can at least tag using the Google Maps interface to tell where I took the pictures.

I don't know if I'd take the iPhone, consider it like a concert, when going to the show, you never wear the t-shirt of the band you're seeing.

Me, I'd actually take the E61i, I have an E62, and for all it's shortcomings, I still think it's better as a phone than my iPhone. Plus, it's not what everyone else has.
