I agree, Metro on a small touch device is good, and being able to drop to the desktop to do "computer stuff" is awesome when you need it.
On a 27" desktop? Oh god, Metro is a nightmare. I've been using StartIsBack but I'm glad there'll be a properly sanctioned start menu soon. Hopefully it will lead to greater adoption of Win8, as besides that one major blunder, is not too bad at all!
Not to mention those touchpad gestures.
Removing start from the desktop was the worst move ever in history.
