For as much as I hate most of what Sony is doing when it comes to PC, nothing beats a game being delivered to your door, sitting on your comfortable couch and just enjoying your game on a big screen.
When you are done with the game you can even sell it and get a good chunk of your money back if you are not a collector.
Sure you can have your PC hooked up to you big screen on the living room but what sort of degenerate does that?
