Re: they've lost already
Intel have missed the boat apart from small places where their ability to integrate stuff at the silicon level might come in handy.
I don't really see that. If anything Intel are constrained by their sheer size, they can't chase down every little niche. If you look at their SoCs they are generally focussed on minimising the BoM on a PC-style system: If you need a few GB of DDR3, SATA, PCIe etc they're good to go. Something that looks less like a PC they don't have much to offer.
ARM and to a lesser extent MIPS win on their diversified supply chain with each vendor tailoring their offering with a much tighter focus. You get a rough idea what you want, say a 32 bitter with this much RAM, this much GPIO and these interfaces. You then go out shopping. Can't do that for Intel.
As Flocke Kroes suggests the price point for Intel is all wrong for the smallest systems: ARM may have a e.g. a $3 offering that pus everything on chip. The Intel offering costs $15 and needs external memory and storage on a high-speed circuit board on top.
