Really liking the multiple desktop idea, will make it easier when I'm editing photos. As I can have Bridge open in one monitor, Photoshop in the other. Then when I want to go to a webpage, swipe to the next desktop and voila! Then swipe back to editing, and I don't have to close/minimise programs.
Definitely a leap forward for the OS.
Ermmm you know Spaces were on there before right?
