I don't think they need to buyout any company. They have the Software with Windows and Office. They are now mobile market with Windows 8 smartphones and the Surface tablets. As long as Window 8 catches on the the mobile arena, they will do just fine. The PC market has been diminishing and those who use PCs and like Windows 7 can stick with it for quite sometime. I have a Windows HTC 8x smartphone and am satisfied with it. It will take time for it to get the apps I and others like.
