Not really, the market has settled on CPU-independent bytecode. I've got a x86 tablet, and you don't notice it at all, other than the Intel logo on the back. As long as there is an ART port it could be MIPS and still have pretty much the same compatibility.
While this is mostly true, it is just untrue enough to cause trouble for a non-negligible number of apps.
The Intel Houdini software used to make Android on X86 possible is a marvel of engineering but it is not perfect. I worked for a company that made an Android tablet around an Intel chip instead of ARM. We were hit with a great number of user reports of certain apps crashing, overheating, or simply refusing to run in the first place. We verified in QA that these apps would work just fine on ARM tablets with the same Android version and similar specs.
To be fair to Intel, they were very good to work with and really did (and do) want to make it work. I have no doubt they will. Eventually.
Actually the market for mobile yes.
But on servers it will actually take a long time to replace ARM. So it's actually a win for customers when these two are rivals since we get cheaper servers or lower tdp on servers and cheaper mobile devices.
Server side, there is an initiative to get rid of Intel as well[0][1] with a PowerPC based chip. It'll be interesting to see if it ends up working, but I think everyone wants to get away from Intel's high prices.
There's only one little problem: the market has settled on ARM and doesn't care anymore.
So how are they gonna play those "both sides" again?
