I just went to a conference where MS showed off a lot of stuff, including Win 8 on a touchscreen.
For presentation lecterns, Windows 8 with touch is awesome. For the desktop the interface is seriously meh. If they had just done a dual mode they would have been so much better off.
Beyond that MS has a ton of really useful tools for enterprise needs. That helps them make money hand over fist. They could probably shut down their whole OS division and still be a corporate behemoth.
