"Upgrade only if you need to, otherwise wait for Win9"2.5 starson by decadre
Pros: Really awesome system tools and background OS features. Quick boot, unbelievably improved task manager, most productivity apps run noticeably quicker.
Win8 is supposed to be intuitive, but it isn't.
Users will learn it and adapt.
What else is there to say when some of the best advice given to people is to down Start8, or Classic Shell which returns UI elements removed from Win7?
Summary: Unless you've tried to RTM and like it, I'd suggest that most people stay with Win7 until they have to upgrade. If you haven't tried Win8 yet, head on out to a electronics store and give a display model a trial run before purchasing a new PC Win8.
Additionally, I may be wrong on this but I think you will still be able to get a new PC with Win7 until sometime in the summer of 2013. So you have sometime to research this still.
