Shares of Microsoft (NASDAQ:MSFT) had one of their best performances in years on news that longtime CEO Steve Ballmer would be relinquishing his grip on the software giant at some point in the next year. If you weren't aware (or couldn't have guessed), Ballmer was a divisive figure, largely because of Microsoft's scant returns during his decade-plus at the helm.

Should investors be snapping up shares of Microsoft, or are shares still dicey? In this video, Fool contributor Andrew Tonner gives his take on how investors should play Microsoft as it enters the post-Ballmer era.
