Here's the thing: I don't want a Playstation. That summs up my whole philosophy on this.
See, it looks like a lot of these manufacturers are insisting that everyone wants one thing that does everything. That's not always true. I've always been of the camp that thinks "Sure, it does 5 things, but it doesn't do any of them well." Sure, sometimes it does some things well, but maybe they're not what you wanted. Like Matt said, if it doesn't work as well as a Tivo, will you ditch the Tivo in favor of having a single device?
So for the most part, I'm a single-use/single-device kind of guy. I'm sure I'll be proved wrong, though.
That said, it looks cool
