The only problem is that the RT also runs Office. I think the Pro looks good and I can't wait to get hands on one, but I suspect that if MS doesn't figure out how to market things it will die a swift death.
On the other hand, MS is famous for continuing to do things they suck at until they get it right. One of the benefits of having deep pockets.
In no wise is this "more of a computer" than an iPad (N7/Fire/&c.) It is a "Windows computer" in exactly the same way that an iPad is an "iOS computer". Thinking that "is a computer" is the same as "runs Windows" is why Microsoft is fighting the desperate, Surface-lead rear-guard action against encroachments on their turf.
