Well yes, I get your point but most users want usability and don't really care what's under the hood. I don't use Windows any more - thankfully (it is living hidden on a partition somewhere if I really need it).
I was concerned about moving Start into the middle but, as per article, it seems you can move it back where it belongs. Corners are hotspots, they are the easiest place to move the mouse, so Start should definitely be in a corner, and bottom left is where people expect it to be. It is, after all, where most users start from.
