I don't care about social features, but I doubt they're mandatory. And there actually is some stuff in there that looks pretty cool. I could see myself actually using some of the spectator features.
Instant game trials (play as it's downloading) is pure win. Suspend mode is something I've been wanting on a console for a long time (obviously handhelds do it). The background downloading stuff isn't sexy, but it does sound useful.
Hardware specs sound great, and they're showing tons of games. Thus far I'm actually pretty impressed. Sony hasn't fucked this one up.
Edit: Oh yeah, actually building remote play into the system and enabling it for all games by default is awesome news. The promise of streaming to any device is also pretty damn cool, but it sounds like that might still be a ways off.
