"Are there any good things about it?"
Tons really. If you're happy to learn.
I would suggest getting a laptop with a touch-screen because it improves the experience about ten-fold.
The search, mentioned above, is really good for finding documents on your computer, settings and programs.
The "snap" views are really good - so, for example, you can have a "Metro" app running in a strip on the right hand side while you do normal desktop things with the rest of your screen. I usually have twitter, messaging or a mail client open at the side for quick access.
The "share" charm is pretty cool - especially if you like to share web pages with others via email, for example - it's super quick at that.
erm, The live tiles are pretty? Sometimes?
The music player is a bit pants, but then, I've never found one I actually like!
