It would, the main reason why apple is still around is because they got their OS to kick ass. Unfortunately it only runs on macs. Now i like macs, in fact I own one. But I know a lot of people who can't afford them and would really benefit from having OS ten on a PC.
SO what we need to do, is get Darwin like linux. You could make all kinds of GUI's for it but it would run everything that OS ten could, but be able to run on most kinds of hardware like Linux.
