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.
I the feature to 'dock up to big screen' is best implemented as an external and optional dock\dongle so as not to increase the price\size\weight for a feature that we may not use every day...
AFAIK, TV out can also be connected to many projectors. This would enable running presentations (and even some demos) from the tablet.
These devices really make you feel like James Bond at times. No if only I can unlock and start my car with the N95 I'd be set.
