I've been reading a thread on another forum, apparently you can't multitask on this? If so, that's a major oversight. And it doesn't have any USB ports?
I can't tell from my quick glance of the links, but does it have some sort of stand or dock? Because I can't see how that would be comfortable to use, unless you're sitting on a bed or sofa, with your knees up and it resting on them.
I was blinded by the 'ooh shiny!' aspect but looking closer, I dunno if it's as good as it looks...
