Impressive thread so far! Given that some (if not most) Zaurus are sold in Japan only, it's not that surprising to see that people here are passionate about their Z, and come from nearly all over the planet!
OK, my turn to introduce myself...
Patrick, 34, married with two kids, and a job which (almost) doesn't involve computers (airline pilot), and live in the south-west of France (Europe).
I've discovered computers at the age of 11 and I've been hooked up since that time, but I somehow managed to make it a leisure only and not my primary job! I've owned a Sinclair ZX81, Amstrad CPC 464, Amiga 500, and then a couple of desktop and laptop PCs. I've been "playing" with Linux since the era where you needed 50 floppies to install the first distribs (back when there was only Slackware/SLS, with version numbers in the 0.92 and such, and CDs were not very common), but never actually "worked" with it - because computers are only a hobby for me!
As far as PDA are concerned, I've owned a Psion 3a, Psion 3c, Palm V, Sony Clie S500C, Sony Clie N700C (both of them were Japanese devices), Sony Clie NX70V (US model, this time), Tungsten T (as a backup/test unit and to use with my Garmin GPS in the car), Handspring Treo 600 (great smartphone, btw), and now a SL-C3000 Zaurus purchased last month.
I've been running a Clie-centered website in the past, and will try to contribute to the Zaurus community with a few Zaurus articles (I write articles in a French PDA website), howtos and docs translations.
If I can manage to install the necessary tools, I'd like also to write a few Qt apps for the Zaurus, but I'd need a Zaurus-based chaintool (which already exist, albeit in a "work in progress" state as far as I could see), and a good "Getting started with Qt programming" book (I've mostly written (simple) PalmOS or C++Builder apps so far...)
My first goal is to write a simple UI to be able to use my GSM/GPRS CF card with the Zaurus (don't feel like using minicom all the time to handle voice calls).
