What a cynical opinion to have. The tech won't improve if they don't actually try.
I've played a couple games on PS Now. I played Final Fantasy 13 a bit on it, a game I've already played, and Alpha Protocol, a game I've never played. FF13 worked great, really nothing to complain about there, was able to play the first couple chapters with no noticeable issues. Alpha Protocol was a bit janky control wise, I'm not sure if that was just the game, or if it came down to the network. Totally playable still, but definitely a detractor.
I probably won't use Now because I already have a PS3 and playing natively will always beat streaming, but it's a pretty nice option for people who don't own a PS3.
