Why won't leave the things as they are now? Why should a Linux or Apple box be better than a Windows one? Why should win any of them. For the sake of future operating systems improvments just let the things as they are. They are improving each other people...! As well as the fight AMD vs Nvidia vs Intel should also exist. Get rid one of them and the innovations will freeze! Also, choosing the right OS or hardware platform is nothing more in these days than a matter of personal taste and needs. Me for example, I would not go away from Windows for gaming and general usage. Also I would never buy an Apple product, and I would use any UX flavour just for dedicated tasks (like servers, gaming servers also, or raw computing).
