I think it's great that MSFT is taking some bold moved with their desktop. Whether or not consumers like the new UI remains to be seen but I can opine this: there had better darn well be a "Windows 7" experience option for new users who just aren't ready to tackle Metro yet but still need to buy a new PC after its release. That's a full desktop with fully functioning Start button, menus, etc.- not some downloadable hack.
Also - beyond the "explore Windows 8" movie they will probably have in the OS there should be a bonafide CBT (computer-based training) course tucked into the release that users can run through to get schooled on the new way of doing things. To leave it purely to IT depts. and other IT pros is just alienating the home and small biz user market.
