Earlier quoted context omitted.
The logical conclusion of the personal computer revolution is the person doesn't control their device?! That's not revolutionary; that's a return to the bad old days...
Yes, because most people don't want a device . They want to be able to watch videos, read books and listen to music. The enabling device is incidental.
Mind you, I'm not saying it won't be cool, and I'm not saying it won't sell many units, (although I have my doubts). I'm just saying this isn't the logical conclusion to the personal computer revolution. A personal computer is, by definition, a general purpose computing device, which this most assuredly is not.
Edit, reply to following comment: How is "it does what I tell it" a narrower definition of enable than "it does what it's allowed to do by the people I bought it from"?
I'm not trying to be flip; I think it looks very sexy. However, it's just a narrow tool, not the end-all of computers.
