Microsoft (MSFT 0.41%) has been frustratingly slow in adapting to the mobile future opening in front of its very eyes, in part for good reason. As much as Microsoft hates to admit it, the company is still very much tied to the PC market, which is very much an outsider in our increasingly mobile world. This unfortunate fact leaves it some very hard decisions to make regarding its two prized product groups, Windows and Office. In world that's largely dominated by Apple and Google, it leaves Microsoft between a rock and a hard place. However, we recently saw an interesting move from Mr. Softy that speaks volumes about its slow acceptance of the new world order. In this video, Fool contributor Andrew Tonner breaks down this move and what it means for investors.
