Windows 8: Smart OS?

I had my first brief look at Windows 8 during the weekend. Microsofts new offering is certainly different and the idea of using the same OS on your PC, tablet and phone certainly would have it's benefits. First impressions is that Windows 8 has a split personality, trying to accomodate PC users at the same time as phone and tablet user. These devices are different in thier nature and that things don't feel as though they quite fit together yet. It is also a big change to go from a menu and windows based system to a solely Smart Phone/Tablet based system and this can mean a substantial learning curve for many users.
Other operating systems are also following the trend with Fedora 17 sporting a distinctly Smart Phone look and feel, but at the same time combining Window/Menu system.
I think that Windows 8 may benefit from the same approach. As it stands Windows 8 may be too big a step for some users. What may be needed is a compromise where Windows 8 still offers a Windows 7 like mode to allow users to bridge the gap. Possibly even a different variant of the system for server based systems where "user experience" may be less of a concern.
Windows 8 is out on the market and packaged with new PCs, the comming 6 months are going to be interesting. Is this going to be a system broadly for home users or will it be picked up by business users too? What ever happens it is a bold move by Microsoft, only time will tell if it was the right move.
