Let me comment on those desktop screenshots individually:
Picture 1: The desktop icons are a HUGE improvement. And I may be alone in this, but I actually find the translucent background windows kind of nice.
Thank God they're finally going to use a new system font! It even looks anti-aliased, and hey, for Windows, that's a huge technical innovation. OTOH, look at the WiMP window in the background: same old clunky font. It may be anti-aliased now, but it's still hard to read, and it's still the same damn font they've been using since Reagan was president.
That Start menu is STILL terrible. After seeing OS X's dock, this is the best they could do???
Picture 2: Nice to see the "Page cannot be displayed" page in IE remains unchanged *chortle* *chortle*. The "Computer Management" window is just as atrocious as ever. That branching system is and always has been clunky, and the icons are still on a par with Mac OS 8.
Picture 5: Oh, dear. That Start menu popup is just as terrible as it ever was. Look at the picture of the guy just to the right of it. He can't even bear to look at it.
Picture 6: Well, IE looks...different. Not better, but different. Wow, they've got tabs...but typically, they've managed to find a way to make it look uglier and clunkier than everybody else's. Hey: the popup dialog box has a drop-shadow. Now where've I seen that before...?
Picture 8: Same damn System Properties window, just looks a tad nicer. I still hate that two-layer tabbed look. The progress bars in the background are nice, but they sure have a, er, ah, OS X look.
Picture 10: Okay, now I've revised my opinion on the translucent windows. What's the point of making the FRONT window transparent? To confuse you???
Overall, it's just about what I expected: a clumsy attempt to imitate OS X. It just goes to prove that they are incapable of doing anything other than copying other companies' stuff -- badly.
I didn't expect to be impressed, and I wasn't disappointed.
