I'm reading this as if you're asking whether or not projection units will ever be a replacement for televisions. Is that right? I don't think that's going to happen. It seems like one of those really cool futuristic ideas that might have been on Back to The Future Part II, but not something that's going to really happen. I just don't think there's the need. TVs are a lot more functional since they can easily be put up in a lot of places.
