My living room TV is a 32" LCD, and I sit about 8.5' away.

I was limited by that size when I bought it since I am still using my old entertainment center, which was designed for a tube TV.
It works ok for normal TV shows, but for a lot of video games and especially movies, it's quite underwhelming. Considering it still works, and the fact that I need to buy some other home theater parts first (like a receiver, center channel, and a more modern entertainment center), it'll probably stick around for quite a while longer.
