So far, whilst I am not brimming with knowledge on the OS, it has received positive feedback from the majority of critics and now Microsoft has set a rather reasonable upgrade fee of just $39.99 US dollars for the Pro version of Windows 8. You qualify for this upgrade if you own XP, Vista or 7 (who even still runs 98 or even older versions of Windows still I don't know). My question is: will you be upgrading to Windows 8?
