Oh yeah!  Typing this from it right now.   Love this thing!  Any PDA you can drop to a command line and do stuff is a big plus in my book.  Love Linux, and am very happy to be able to take it with me. We're a strange breed, spoonman...  Not too many own one of these gems.    And it looks like Sharp, who didn't do too good of a job with marketing these things in the first place, has ended Zaurus sales in the US.  noooo!  *sigh*  What could have been!  If anything ever happens to this thing, I 'll just order a Japanese model from an importer (someone like these guys:  
http://www.dynamism.com/pda.shtml) where the Z is still alive and well.  I'd love to have one of the c3000 clamshell models with the hard drive.  $$$ but these PDA's do more of what I need than their cheaper MS/Palm/whoever counterparts, mainly in regards to hooking up with the other linux machines on my network.  Plus the built-in keyboard - tiny, but I'll never own another PDA without one!  The cost though, is more than many notebooks, but a notebook just isn't the same. I love this thing!  Unsupported, not much stuff out there for it...  But I find this oddball handheld is the perfect one for me.  And of course, back to the subject at hand...  see attachment!
