I'm already using Windows 8. Sure, it's different. They have taken some things out (like the Start menu and MPEG2 codecs) and improved others (like the multi-monitor taskbar). But I feel it's about the same as Windows 7 if you ignore all or most of the Start screen 'apps' and just use it as a program launcher. I know the the Metro new interface was designed for touch operation but is a little clunky to use with a mouse (new computers being made for Christmas this year should have touchscreens). The apps there are not yet up to the level of other Microsoft desktop applications (like the Music app not reading metadata from MP3s or the Video app showing all my pr0n alongside my movies). And there aren't a lot of apps in the Store yet either. I haven't done much testing of games but Steam was working and some games too. Didn't test ArmA 2 though.
