I would agree about the Metro interface. When Windows 8 lands on desktops in corporations, the screams are going to be insane. I just installed Windows 8 (under VMware Fusion) and played with for about 1/2 hour. It was a very frustrating experience. This is my personal opinion: the transition from Windows XP/7 to Mac OS X will be easier for most people than the move to Windows 8.
