Cloudman: yeah basically. Custom backgrounds, 3D, DLNA, mp3s, photos and videos, better organisation (Imo). And even beyond features, the PS3 is a better Bluray player and better at Netflix for image quality.
It's kinda crazy. The PS4 feels very closed off and unremarkable, the PS3 was open ended and very friendly to multimedia. I kinda feel like PS4 stripped out great stuff for no good reason.
