The best we'd be able to do is create our own custom Linux-based distribution.
Even that would be a welcome addition to desktop users should MS not relent on this Metro UI thing.... and Stardock would have a vested interest to develop ObjectDesktop, etc, for Linux based PC's. Yeah, I know it's unlikely to happen, but the dream is free.
The biggest worry we have remains the attempt to merge a desktop experience and a mobile experience into a one-size fits all solution complete with its own walled garden.
Yes, that is the concern I have, that MS seems determined we'll use Metro, like it or not. Win 8 has several advantages over Win 7, and I really like them, but I really do not want to have to deal with that interface at boot, have no access to a start button/menu or be dependent on MS' app store to gain access to useful tools not included in the OS. These issues are what stand between me and purchasing a Win 8 license, so if MS remains intent on disabling all 3rd party apps that provide a Win 7-like experience, then there will be no sale.
