No, a touchscreen tv would be horrible. That goes back to the RCA days where you had to get up and go to the tv to change the channels using the knob.
There's nothing wrong with the remote, just that it is starting to get very confusing to use (too many buttons). If Apple can find a way to make the modern remote less complex that would be a step in the right direction.
Sorry, just noticed this. Okay - how about this: organising your screen with various different views of the same sports match. So imagine you're watching a game of Rugby and "sports broadcasts of the future", given they have access to digital TV channels that are far less restricted by physical bandwidth, broadcast continuous streams of the coach, the bench, the score board, the commentators, the crowd and different camera angles on different streams, as well as the main "professionally edited" stream. You drag windows around and resize them to organise the various channels you're interested in into a custom viewing configuration.
