Nothing wrong with Windows 8 so far. I havent seen hardly anyone killing it either. Maybe the pattern of "one bad then one good" has ended? 2 winners in a row.
I split up my 1 Tb HDD before installing Win 8 and still have Win 7 on my other half. But I only use the win 8 side. I originally did that in case Win 8 bit the big one. But I have been happy. And only paid 14.99 for my key as well. :-)
