The wait for much awaited windows 7 is over now. Microsoft releases Windows 7 today. The interest for the new OS from Microsoft has been huge, making Windows 7 the biggest pre-order item in the history of Amazon UK and a perpetual trending topic on Twitter. If you are struggling with Windows Vista, or just looking for an excuse to buy a new machine or upgrade on hardware, you have the excuse now, Windows 7 is here! Head on to http://www.microsoft.com/windows/windows-7/ the official page of Windows 7 to see the enticing new features or what you might be missing by sticking to Windows xp. The vista annoyances & sluggishness have been fixed to some good extent and the users find their systems more responsive and a bit speedier overall. If you’re interested in making the switch, the price is $319 for Windows 7 Ultimate, and $299 for the Professional version ($219 and $199 for the upgrade, respectively). Windows 7 Home Premium will set you back $199, and an upgrade from either Vista or XP will cost you $119. For me, I’ll stick to my good old Windows XP for quite some time before purchasing the upgrade.
