Given what other apps have done, I don't see why the features could not run on the Intel Macs. I don't really care about these features, but at the same time Apple is starting a cull and it isn't cool when I have just paid over three grand for a Mac a year and a bit ago. That being said I like to play Windows games every now and then, and as this is currently not possible on Apple CPUs with anywhere near full performance (Not that this is a good set up or nor do I expect Macs should be able to, but it was a nice touch in the old Intels) naturally I will probably be moving away from Apple when the time comes in four or so years.
The iPhone has already gone and I have an android, although that was just to save cash in our new world. Maybe Apple will release the features one day on the intel Macs, who knows. But I am generally looking to move away from Apple as they have lost what attracted me to them all those years ago.
I used to like the simple and basic features of Apple products, and I liked the rules of the design. All this is going out of the window. I am sure they will be fine, as they seem to be attracting many new people to replace the ones lost. But that was my view on the matter.
