I've long said that if Apple would allow MacOS to be installed on desktop computers made by anyone, but being certified - then it would boost their market share exponentially and in turn boost iPhone and iPad sales even more.<p>It would attract more developers and in turn better quality software and more software means more customers.
As a long time fan of my Macbooks, I'm really excited about this. This could finally kick one of the other manufacturers hard enough (Lenovo, Dell, HP) to make a seriously good device. The MS Surface Pro series is already pretty solid, but Windows is just not there yet. I don't think it will be Ubuntu taking the cake, but with some better software, I'd happily switch away from macOS.
