We *do* have a big flat screen HD TV, but it lives in DH's and my bedroom and was bought SOLELY so DH could play his xbox (he was using a regular TV but apparently he could barely play the new console because the graphics need an HD TV).

We too have a problem with fiddle-fingers in this house, so no way would we put the expensive TV in the lounge room - it would end up smashed within a week, I guarantee it. DH and I are racking our brains trying to work out how to stop DD1 getting near it... but, we know there is no solution apart from making her live outside with the dog lol. So the TV stays in our room until she turns 13 lol.
