“We’ve ushered in a new era of cloud computing, embraced mobility, are attempting to transform entertainment, and Windows is the heart and soul of Microsoft”
This explains why Microsoft is in a downwards spiral (and until further details from Surface are provided i don’t think that will save it either). Windows should never have become “heart and soul” of Microsoft. Office is what people really need/want, Windows is just a tool to an end, or a tool for the use of another tool. And not a really good one.
As long as you can do your Office work, in a compatible and “usual” way, it really doesn’t matter if you have Windows, Linux, Mac or some other OS. Focusing on Windows instead of Office will be the key event of Microsoft downfall.
