Apple exists today because they aren't part of the race to the bottom. They sell hardware, and make a nice penny off it. They make good software to justify charging for their expensive hardware and this process serves them and their userbase just swimmingly. Please continue paying half the price, and having the discount software experience as well (why the hell would you switch if you didn't think the option was better than what you have currently? This is how capitalism works - you get what you pay for)
Apple has no reason to license their OS, and as an Apple user I hope they don't. I don't mind paying more for their product and I don't want the quality to drop because some people simultaneously complain they can't use the allegedly "better" option because they don't think it is worth paying more for. It's worth more to me and many others. If it isn't to you, stick to paying for the cheap computers and stop whining already.
This is not to say I'm not for Apple lowering prices, of course I would be, but I don't consider what they ask now to be an unreasonable difference between other manufacturers because to me I'm truly getting something better and it is far and away worth the $
