There's potential in this idea. (BTW: my first computer was an Atari 400 that was, of course, connected to our TV, so I'm used to TVs being computer monitors)

Probably, if you really want an mouse, a keyboard and a bigger screen, proper use of X-forwarding to a *real* monitor would be the better way to go (it's still an unsolved mystery how to do this).

But for certain use cases, the TV (a large TV) clearly wins. Also, the idea of using the camera phone as a mouse is great: After all, most of us do use their tablets together with a mobile phone anyway. Why not make extra use of it?

The only thing I don't feel comfortable with is that it would probably add to the size/weight of the device yet again. (Or wouldn't it? I'm not sure.) I want my tablets small, smaller, smallest, every millimeter counts.
