I think the rounded edge is just a gimmick. If they are goign to round anyways, why take part of the edge off. It's just limiting the ski. In the east, I want a good sharp edge for riding ice and pipe. And they don't roudn them because it helps with not catching edges. If you catch an edge on metal, you have serious issues.
