Hype and misconceptions. I've tried it today, after a few hours of working with it, i conclude that it is usable, but nothing that special. It comes with powershell, so i didn't have to install it myself, but other than that, i didn't notice anything "must have". The gui has some nice little things added to it, and some of theme are useful, but noting groundbreaking, just another UI you can get used to. I guess its the sum of the little things that we can judge it. I might be wrong, I've only tested it for two hours, 20 minutes of which i played chess.

the taskbar is pretty cool, some people are going to have trouble with it thou.
