Yeah, they've been on the SE site for a while now. Very nice indeed!
I really want the K800. the camrea looks awesome, 3.2mp on a phone! But by the time my K750i is due for upgrade I'm sure there'll be a whole heap of newer ones out. They bring new ones out far too quicly!
As a side note I've noticed they've slightly changed the design of the annoying sticky joystick on most models, which is definately a good thing!
