how about "a not-very-good-but serviceable-in-a-pinch-and-really-portable" desktop replacement?
really.
I COULD do most of my desktop stuff on my z (though a/v encoding, and compiling, would be torture). In combo with a remote server, it gets better... but, for example, I think replacing the secrataries' and accountants' desktops with zaurii would cause a severe drop in productivity.
on the other hand, i'd rather travel with my z than a desktop, or even a laptop. Even w/ a folding keyboard and the power supply and bits o cable the z goes into a pretty small and light package--- and I'll happily trade screensize (to a point) for portability. the 6k has enough screen to "get by" on, and the saving in weight and space are terrific.
maybe a secion of packaging (cases and case hacks) configuration and peripherals?
