Home Theatre.. 49 inch flatscreen, 5.1 setup, the whole shebang.. often times I even game on it.
I can also watch movies from downstairs on my Xbox (which I like to do) on a 27-inch. This is where I do all gaming if not upstairs.
I also have my little Laptop that I use for a computer in my room. It's got a DVD drive, but I mostly download movies and watch them here at night with some really good headphones.
