I have a PS3 but hardly go online with it. I've been online with it once since I've had it, and that was when the fat PS3's still had SACD playback, etc.
I use it mostly at the moment for playing videos/DVD's.
Its a great Blu-ray player too, and one of the cheapest out there, which is fully upgradeable.
To be honest, it's worth it just for that, but the games can be good too, but I tend to use my 360 for a lot of that since it's in my room and readily accessible to my monitor, etc
