Well, DLP is not an option for me.
I have a pretty narrow living room, and currently have 11 feet from the couch to the wall. I don't need to have a chunk of that space be taken up by a TV. Also, because i am gonna be sitting about 10 feet away from the TV, i am looking at 46". I've taped up the dimensions on the wall, and it seems to be a good size for my living room. I guess i just need to go and really watch
And yeah, i realized cables will be harder to access, but after the initial hookup, how often do you really switch cables?
EDIT: I just looked at
this chart that i found a while ago, and it seems that in order for me to benefit from a 1080p TV, i'd need to get something over 50". Since that's not happening, maybe 720p is a decent option
