Microsoft Prepares Window 8 for Battle Against the iPad 

Microsoft is set to unveil the next generation of Windows.  The new operating system, currently known asWindows 8, is the tech giant’s attempt to regain ground that it has lost to Apple, which surpassed Microsoft last year as the world’s most valuable company.

It isn’t the MacBook or Mac OS X Lion that has Microsoft executives worried, though. It’s the sheer dominance of the iPad.
