Sharp Zaurus ZR-3000. Good suggestion ... it looks kinda "primitive", but that's probably only because of the old monocrystal screen. It does have a clamshell keyboard and 4.0x2.6" screen mount. I can't seem to find any vendors who carry parts for this model, though. Here's a few others that caught my eye: CyberBank PC-EPhone III, HTC Omni. I'm also thinking about UMPC cases (maybe). The greater dimensions would give a lot more space and surface area to plug into - I don't know a lot about what's out there. There's also the option <sigh> of scaling down to a smaller screen (say, 2.8") and crunching down on hardware; but hugely broadening my options to hundreds of cellphone cases, like the HTC Kaiser 100 or the HTC Hermes 200. I don't really like this option, but it is viable. I suppose I could even trick out an iPod Nano case ... heehee, what a way to dominate your music and pwn that iTechno yuppy jerk at work. Any thoughts on Treo cases? Or any thoughts on cases that are solid, flimsy, worth checking, worth avoiding? Anything *small?* with a 4" display (or at least 4" overall facing) and a folding, slide, or clamshell QWERTY on it? I don't care about any specs for the device, screen, buttons ... I just want to steal the case for my own nefarious needs.
