We have just moved house so just 1 tv at the moment, a quite old, Phillips 28" flat screen CRT in the living room, still think its a quality tv though. We have Telewest cable on that.
My plan is to get a wall mounted 32" HD LCD in the bedroom, linked to a mac mini with frontrow.
I will get a nice 40" for the living room, an xbox linked to a media centre pc. That my immediate plan then wanna get a smaller LCD wall mounted in my office too for media stuff.
