well when it comes to BluRay play back it is just as good, if not better than the average BluRay player. As for additional functions the ps3 can of course play ps3 games. In addition to that you can download games and movies from the psn, you can surf the internet, you can use it as a media player (music, pictures, ect..), and you can also connect it to your pc to transfer media to and from it. However the ps3 slim DOES NOT have the ability to install linux, which sucks but I am sure Sony had a reason.
