windows 8 is nice looking and have some small improvements, like having pause option in the copy menu or the redesigned task manager or upgrading windows defender to an antivirus suite. But I really hate the metro UI. It is not user friendly at all.Everything about windows8 is hype, it is atleast NOT BETTER than windows 7.
As an OS it has improved in areas which are much welcomed by the community in large..
The hype was to make Metro UI a success, which never clicked. And as per the small improvements as u rightly pointed out (also, the detailed task manager for instance) are certainly a boon.
IMO, Win 7 (original) to win 8 upgrade isnt worth. But for a person like me who wants take a step forward away from piracy for the first time OS buy, this is the right time.
I have stopped pirating games long time back and now even my OS is original (sigh). So people who are still not convinced, put your bucks eyes closed if you are a first time OS buyer.
