I really disagree that it isn't possible without compromise. The Surface Pro, Surface Book, and iPad Pro all have hardware capable enough of providing both experiences for many users. If you, right now, built an iOS virtual machine into a touchscreen "hybrid" Mac/iPad, it would be a somewhat usable system. Focus some engineering efforts on combining system settings, some sort of filesystem/local iCloud integration, and it would be a very usable system. What compromises would have to be made that aren't already made worse by the fact that you have to have two separate devices? It could be argued that Apple have dropped the ball in software probably precisely because their platforms have diverged so much, and even more so with Swift, iOS moving away from older APIs. The argument that I'm trying to make is that if you treat "the system" as a continuum, there is no "side" that gets more attention. Some things will focus a little more on the touch side, other things will focus on the desktop side, and many will take advantage of the inbetween. There are little glimpses of this in Windows 10, and a few in Windows 8. Microsoft lacked the mobile ecosystem to pull it off, but I don't for one moment believe that it isn't possible.
