What folks years ago predicted has happened. M$ will sell use of GNU/Linux on its cloud services. When they sell GNU/Linux through their OEM-”partners”, the world will be a lot closer to having a proper market for PCs. That is likely to happen but not until they have their hat handed to them with “8″.
I expect eventually to see M$ either coopt a distro as “partner” or develop its own distro. Either will be an improvement over exclusivity on retail shelves. For the moment, this seems like history happening, appropriate to the anniversary of D-Day.
BTW, this is the ultimate proof that anyone can make money from GNU/Linux when The Great Satan of IT can do it.
