The RT version is up for pre order. I'm waiting for a pro version windows 8 to my collection.

Still not sure I get the surface. But a full desktop environment is on my mind. And As I understands it, not yet confirmed or denied, and you can also load your favorite Linux distribution if you wants to.

I think the world will change. The change will be that desktop and tablets,running the same os and applications. That's great devices gets more powerful.
