YOU move to ARM. I won't miss you. 
That would be the dumbest move Apple could possibly make. It would isolate Apple once again to the realm of IRRELEVANCE (i.e. No Intel = No easy Windows porting and no Boot Camp or VMWare booting into the world STANDARD [whether one likes it or not] of Windows OS) just as in the PPC days, obliterate any remaining market share (still PATHETIC at only 7-11% depending on whom you ask) and along with the coming failure of the iPhone7 (in relative terms), send Apple even faster down its one-way ticket to total and utter oblivion. And unless Jesus himself comes to raise Steve Jobs from the dead, there will be NO ONE to save Apple's hide this time around (Cook is already doing a great job of killing Apple by sliding on iPhone sales instead of actual innovation and letting the Mac Pro die another slow death of NO UPDATES and getting rid of Scott Forestall who created the PERFECT iOS GUI and putting Jony Ive in charge of the GUI which more than just its cartoonish looks is far FAR more a PITA to use.
Just look at the revised Music interface to see what I mean (duplicated play buttons, sliding "art" screen so they can shove notifications to please PLEASE join Apple Music in your face. Moving the Artist/Album/Songs selector to part of the sliding list (where you can't select it at any time) JUST so they can put "Apple Music" (which I don't use and will NEVER use) where you want the damn Artist/Album button to be with NO WAY TO CHANGE IT TO SOMETHING USEFUL/FUNCTIONAL/WORTHWHILE!!!! And they say Windows Phone sucks? God, tell me that Android isn't so stupidly laid out as iOS8/9 and I'll switch for good (oh wait; I already bought an "irrelevant" Windows Phone because it was DIRT CHEAP and does the job for all anyone actually needs on a smart phone (email, browse, music, videos and phone).
Yeah, go ahead and move to ARM and see where it gets you. ALL current Mac software will stop working. NO ONE will bother to replace it this time because instead of moving towards sanity, you're moving AWAY from it, all to get CPUs that update (currently) faster and yet are still playing catch-up to Intel? Since when are CPUs on Macs not fast enough? Since when are they the limiting factor here??? We have the absolute fracking WORST GPUs in the Universe (and couldn't play many modern games anywhere near 4k, let alone 5K resolutions even if they were available and FORGET ABOUT VIRTUAL REALITY ALTOGETHER) and you are worried about the CPU. To do what? Run a web browser? Run Microsoft Office faster? How much power do you need for your average productivity software?
If Apple moves to ARM for OS X, Microsoft will gain about 60 MILLION new Windows 10 users almost overnight (i.e. the entire user base of OS X). Everyone talks about Linux, but no one actually uses it except no-life nerds and crazy people that think everyone should share everything for free and live off good will instead of cold hard cash (even though it won't pay the bills and won't put food on your table).
If Apple were smart, they'd start making Macs with high-powered GPUs and pushing for the next BIG THING which is obviously Virtual Reality. Anyone who has seen anything from a VR "Vacation from your couch" video to an adult film VR experience already KNOWS it's the future. Apple should be RACING towards this goal, not contemplating turning OS X into iOS Mark II. For now, the hardware to drive VR is going to need to be full sized desktop stuff, but you want the goggles wireless. So high-speed networking plus one high-powered GPU over-stuffed computer is what is needed. The CPU is secondary to the GPU for VR by FAR. It would also solve gaming for OS X at the same time for conventional games (current GPUs are absolute garbage).
