that thing will be $500 with like a 30 minute battery it's wicked cool, but I think they're trying a little too hard the rear touch screens + accelerometers ? overkill having said that, I want one
I don't really do the handheld thing either. I have a PSP (which I bricked and then fixed), but only really use it for traveling.
