The product seems like a solution in search of a problem to solve. It seems that people who want mobile utilities will get them from their cellphone (which is really more like a mini-computer than a phone anymore), and those who want more than that will want a full OS.
Not to say that the technology isn’t cool, but once we get past the gee-whiz factor I can’t think of what else it would be useful for.
Its basically a big iTouch with a touch more functionality... I personally can;t see much use for this as its too big to be portable, and anyplace I’m taking a backpack or whatnot to hold it, I can just take my laptop instead. And have even more functionality!
