I'm actually considering going back to Windows 7 as performance of 8.1 isn't as good as 7 for me. The nasty colors/windows and fugly metro interface is possible to get used to, but still ugly, slower and pointless.
While 8 seems just as stable as 7, I can't help feel that 8/8.1 is the newest version of ME/Vista

At least, I'm pretty sure that's how it'll go down in history...
