Maybe a ray of hope for Windows 9? (personally I doubt it... but boy would it be cool...)
Read the whole storyMicrosoft's vision of how PCs work in the post-PC era is based on Windows 8. In order for people to experience that vision, they have to have it on their devices. Currently, the only way for the user to do that is something extremely intentional -- they have to go out of their way to buy new hardware or upgrade it. Those twin barriers of "payment" and "hassle" acts as an enormous drag against delivery of Microsoft's complex vision.
