Apple could make a fortune if they released x86 OSX as a paid/subscription model OS without the hardware paywall.
They used to charge for their OS, it was pennies, I remember getting a free upgrade to Snow Leopard because my recent MBP came with Leopard, then paid £36 for Lion, then £24 for Mountain Lion due to previously paying for the last one, then £12 for Mavericks due to paying before, then came upgrade time again and the App Store told me that I no longer had to pay!
Mental considering you can legit share your install disc/download license with upto 5 people in your household legally at the time... No serial numbers, no BS registration... Nothing. Just ONE version for everyone, and a Server version for those that want it. Simples. Cant beat that.
Never had any stability issues, IIRC my original 2008 unibody MBP was on solidly for something stupid like 384 days when I checked once, never crashed/froze...
Even with hackintoshes, of which I've built since Leopard days, I've never had any issues.
Funnily enough it was hackintoshes that got me to buy a genuine mac years later after being so impressed, as the Unibody chassis/screen/touchpad was WAY ahead of it's time and no one was making laser cut milled billet ally chassis/glass trackpad/screens etc etc... Now everyone does, go figure...
Not an Apple fanboy, but when you make a chassis that good, that can literally run any os without restriction, is fully upgradable like any windows laptop, and is thin ASF for it's time, you can't say no, and it was the same price as my last Dell, the only 'trick' I did was buy the one with the smallest HDD/Ram and buy that seperately... Just like people do with PC's/laptops...
Hackintoshes are so seamlessly easy/stable to setup now thanks to the amazing community and projects such as OpenCore, that even making something that never existed on a mac like a Ryzentosh, is childs play.
So I would happily make a 1 off payment if it was along the old school price range mindset, I did love it when they decided to just give it to people for free when it was bugger all to start with, that was a nice touch. As is the no serial/registration/share it with 5 people/1 version for all/1 for server.
