if you're in the market for a smartphone, have you thought about the Nokia E90 with the clamshell design? Man, that's got the lot: GPS, 3 mpx camera, high-quality video, wi-fi, bluetooth, decent keyboard. Oh, and it's a phone.

Don't think it's out yet, but will be in the next few months. The keyboard is the real selling point for me, as using those tiny keys like on the T830 or Sony Ericsson P990 (my current phone) can be quite painful - and inaccurate!
Mind you, I'm a big fan of Fujitsu as I've got one of their laptops, so I'm sure the T830 would be reliable at least.
