I'm not spinning, and no ARM's size isn't an advantage (I didn't say it was).
Intel wants to build everything in volume. Intel's current business model does not benefit from specialization or customization. Intel needs to make a large profit on each CPU sold. Intel drove out of the market anyone who could build a chipset since it interfered with volume and profits. Intel would be happiest with their current business model if they built one laptop motherboard, one server motherboard, and one desktop motherboard.
This is a strategy built for the PC market. It does not have anything to do with the current mobile market (non-laptop).
Samsung and Apple want to build the best end product. They want to put things in and leave things out. They cannot do that with Intel, but can do that with ARM. Intel doesn't allow or want customized SoC. Apple and Samsung do. Other vendors also make their own SoC from ARM cores. These SoCs provide different benefits. Having a common instruction set allows switching to another SoC when needed.
