It might even kill the AppleTV?
An

TV upgrade is certainly desirable. But this idea that the tablet will be the next-gen

TV makes sense only for single people living alone. As soon as you take the tablet with you, anyone else living at your home will no longer have a (tablet)

TV (replacement). I just don't see the tablet killing the

TV for this simple reason. How it might be done is to make the tablet dock hold the

TV functionality so that it is still an

TV even when the tablet has left the building, but then you are closer to having 2 dedicated, separate devices.
Similarly, the tablet as the ultimate all-in-one remote has merit... if you are single living alone. As soon as you take it with you, everyone else can't use the home AV stuff because the remote is missing. Besides, there are excellent, learn remotes that can be all-in-ones, which are made to survive being sat upon and dropped on the ground. How often does your current remotes hit the floor, get sat upon, end up in the dog's mouth, etc? Do you really picture this tablet being tough enough to fill this function? And do you want something as fragile as this will likely be at risk of being dropped, sat upon, etc?
Sure, the tablet of our imaginations can be all kinds of wonderful things. But when you step forward with concepts like practicality, and situations beyond your own (such as buyers who aren't single living alone), a lot of these ideas seem to be challenged.
I'm first in line for a next-gen (1080p capable)

TV. And I already own a terrific all-in-one learn remote from Universal Remotes (that cost a whole lot less than this tablet will likely cost). When I travel, the

TV and the remote the family is used to using stays at home (so they can still enjoy the use of such things).
If we're going to think about the mobility of this device, how that mobility affects others in the household means everyone at home probably needs one, or that mobility doesn't make the applications for it as broad as some of these imaginings make it out to be.
