Op, I left your wheel at Bikechain after you no showed me (!!!!).
Couple quick words about the Zaurus (I should have known better than to mention it here :-o ).
I have a 5500 which I've had for around 2 1/2 years. Newest version is the SL-C3200
http://tinyurl.com/2zso4c. Sharp no longer distributes in North America because the Zaurus didn't make much of an impact and no one was buying them, mostly due to poor software availability relative to Palm's at the time and, IMO, a crappy stock battery. With 64 M flash, even now it still spanks much of the competition. I got it because I wanted something with Linux on it and it still suits my needs. I'm not sure I'd recommend one for a non-geek and I'd definitely recommend an upgraded battery on or a battery pack for extended travel. I've seen 5500's go for as low as $80 CAD on ebay.
