I think you have right, that people should have home computers for home instead of office-centric pc's, but be honest to yourself: It's no market for that. It's sadly nowdays a dead-bored idea. :( There are no games for MOS (compared to pc), no educational programs (mathematica, mathlab, etc), even an usable web-browser. And I think no one wants a slow and old machine for home for more money than the fast and well-supported pcs.
