I recently (end of September) purchased a C1000 through Conics.net. (I'd owned an SL-5500 for several years and had been shopping for a Cxx00 for a while.) I installed pdaXii13 Akita and zgcc on my C1000 and, with just one keyboard hiccup, I was on my way, happily coding for an extra 1.5 hours a day on my city's standing-room-only trains.
I love the ability to thumb-type. I love the small size. The battery life is amazing (I go several sessions of heavy use -- recompiling VERY often -- without recharging). The screen is beautiful.
Unfortunately, I could really use more power. A heftier CPU and more RAM would increase my productivity quite a bit -- I spend more time staring out the window waiting for a recompile than I do writing code at times, and while writing games on the Z certainly adds to the design / code challenge and forces me to optimize early and often (not a bad thing when you're a one-man shop), I'd like my unoptimized code to at least RUN on the thing. It's a PITA to need to optimize before I can see results. I have already bumped the CPU to 624Mhz.
In short: I'd like to find a thumb-typeable PC with a decent screen, low weight, better CPU and more RAM. I'd be willing to go about 3x what I paid for the Z (about $400). I've shopped around but most stuff is expensive and / or rare. Figured I'd see if anyone had gone the same route already. Any suggestions? Ideas? Experiences?
Also, if there's anything I can do to speed up the Zaurus that would be great to hear as well.
Thanks, and cheers.
