The Associated Press is calling Windows 8 Steve Ballmers Make-or-break moment. Is Microsoft’s CEO really that close to getting the ax to where the success or failure of this OS can put his job on the line? Windows 8 is a great OS, but convincing the masses and enterprises that it’s a great OS is going to be the real test.

Ballmer’s margin for error is slim after being consistently outpaced by Apple and Google in his nearly 13 years as CEO. During his tenure, Microsoft’s stock has lost nearly half its value, wiping out more than $200 billion in shareholder wealth.
