And focussing on performance is a great idea--when has any company ever had the backbone to do that before, in a major software release?
It's not a new feature, it's an existing feature, but for me the experience is painful. It's not sexy but it's smart and it's not like they were going to release a new feature-filled OS by next year anyway. Better to have a solid base on which to innovate even further later down the road.
