[quote name='guardian_owl']I get where the poster is coming from though, if you are at home and have to tie up the PS3 anyway, why not just play it on the system? I guess if you wanted to play Demon's Souls on the toilet there's that, but that's kind of a niche reason.[/QUOTE]
What if your TV is being used by someone else, you want to have something else on at the same time, or if you're in another part of your house/apartment while still wanting to game? Then you could stream a game, video, music, etc. to your Vita without needing to tie up the TV or go without it for a while. I don't think the point of Remote Play is to let you play games, videos, music, etc. that are on your PS3 exclusively with a Vita at all times, but when you won't be near your system or when you need to use the TV for something else and don't want to be blocked from using your PS3.
