Blu-ray players

Game demos, game updates, game saves, game DLC, game installs... If you don't play, no need to buy one with a big HDD.

Yeah, you won't need a large HD if you won't be playing many games. Just for OS updates and other stuff. The PS3 is also great for use as a media streamer too, so you could hold videos and music on another computer and stream it when needed.

If you are mostly going to be using it for watching Blu-Ray discs then invest in the PS3 bluetooth remote control because it makes it much easier to control DVD and BD video discs without needing to hold a game controller.
