Voted dislike.
First, I see no urgent need to upgrade from Windows 7 at the moment.
Second, as many have already said here and elsewhere, I just don't get the new desktop philosophy (if there is any). Cramming two completely different UI into one OS which I am forced to use if I don't write scripts seems silly. It would have been nice to give the user an option to select their default login UI (boot to desktop vs. boot to Metro).
I don't know if this is still true, but I have seen in reviews that some system settings are only accessible from metro, so I am really forced to go back and forth.
IMO they should have gone the iOS route and build separate UI for desktop and mobile, sharing just a common codebase.
