I'm buying a TV for my new apartment (moving in with gf) and need advice. I've settled on a model/brand but need to decide on size. I'll be in a NYC apartment (decent sized which means small anywhere else) with about 7-10 feet between couch and tv. I have my eyes on a 42 and 47 inch LCD tv. My nerd sense says get the 47 but pragmatic me says that might be too much and the 42 may be a better choice. Both are reasonably priced. I'll use this for bluray movies, hd sports, ps3, and xbox.
