Blah blah blah and Apple copied Xerox. The only thing that matters is if it is improved or not. The interface looks like it is designed for mentally challenged blind children.
The "enhanced" Start Menu is a joke. I already have a place for my frequently used programs (the Windows toolbar and 3 additional one click cascade buttons of about 25 programs each) and rarely use the Start Menu anyway. When I used ME I always disabled the re-ordering "feature". In fact, I renamed my Start Menu to "Go" and changed the Windows logo to a smiley face. And jiminy, look at the size they think people want to use it at. So, ideally (in their opine) if you want to run something from the Start Menu, instead of moving the mouse cursor 1 inch you have to move it half way across the screen?!
As for that My Pictures type crap, well that's just more crap in the fine tradition of Paint and Minesweeper and that cheesy Movie Maker for people that apparently have no access to the world of non-MS throw-in products, or no clue that real useful and/or entertaining programs even exist.
