I actually like it when I need to use it. Hitting the windows key and typing what I want is very useful and I find it more functional than what was in Windows 7. I don't really use Metro for much more than that, but on a desktop I don't really need to use it for anything else. The Desktop app runs great and is lighter than Windows 7, which was a really solid operating system.

Edit: Also, give some time for it, its app market and hardware designed for it to mature.
