I want something future-proof when buying something new (of course).
Same here, unfortunately nothing comparable has shown up yet.
And Sharp seems to be manufacturing at least the C1000 still (as Trisoft reported recently), so for the time being, and a couple of more years we are good.
What I like most about the Zaurus is it's form factor (the clamshell) in combination with it's size and extensibility. Most of the time I only use it as an agenda. For the rest of the time I try to develop a bit here and there, and experiment with all kinds of software and learning Linux. It's my mini-laptop I guess.
Same here.
In addition, I have all my development e-books from Manning and the Pragmatic Programmers along with many magazines from the ACM Digital Library. I have both Ruby/Rails and Java/Ant prototyping environments conveniently setup (thanks for your jamvm, classpath and j2me packages, btw). I also ripped many of my CDs and transferred them. I often use the dictionaries, etc...
I sold my notebook as the Z. mostly replaces it. For real work I have a dual Opteron workstation at home.
What I hate is the inability of synchronisation with my work agenda and mail (Exchange server). If that could be fixed a new Zaurus is definitely my PDA for the next few years.
Well, sync is not possible with Lotus Notes used in my current project either... not that it will make you feel better... I am currently looking into web/server based calendar options to sync with KO/PI.
The prices on the Z. are really falling down, btw.
I bought recently a SL-C3000 with Ambicom WiFi and Socket Bluetooth cards as a gift for my girlfriend's birthday for $275 from the US eBay.
So I would say get a Cxxxx model, let me know if I can be of assistance...
