1. Offer Windows Blue on a USB memory stick, since more and more systems, Tablets and Laptops, don't come w/a DVD.
2. When installing on the Surface Pro, only load the drivers needed, in order to conserve as much SSD memory space as possible on it. Keep the install as clean, and as small possible.
3. The return of the old Start Menu, as an option. While some here may not like it, many of us still do.
4. Release a Windows Blue version SpecificallyTuned to the Surface Pro, and it's built in hardware, and to it's fullest, for it's maximum performance, much like Microsoft does w/the Xbox 360, and it's hardware.
