Well, just watched a review of it, and many of the features advertised as 'new' I already have, such as the desktop button, or I don't really think I'll need much. However the dragging windows to the top to maximize them is useful, but just lazy

And I'm not keen on the new start menu. I hate the way it is in Vista, in XP I can see all my programs at once, whereas Vista meant I had to scroll through to find what I wanted-which I quite often missed.
The math writer thing was just fail. He tried to write 7 and it came out as >. Pi came out as some random symbols he didn't even know
