I like this cost/benefit analysis. Often people forget that, when building a product, there are tons of features wanted, with different costs, and different benefits. Its not easy todo the right thing.

They already do. Stardock, for instance, has built a pretty good business providing power-user enhancements to Windows (see http://www.stardock.com/products/?from=nav).
