The main CPU is a distraction
>Actually, desktop computers were ARM's original market.
Yes, ostensibly, but Acorn's marketing department had been previously fired by the Sirius Cybernetics Corporation. They (the marketing department) could only conceive of selling into education, and even higher education was an unattainable leap of the collective imagination (hence the fact the UN*X version only sold 200 copies.)
Someone who had been working on the UN*X version uttered a phrase I will never forget; "one in every washing machine."
I actually prefer the even more ironic, "two in every washing machine." The main CPU is an irrelevance - even if every netbook and smartphone in the world uses an Atom as the main CPU there will still be ARM processors, probably *many* ARM processors, in the machine.
The article suggests that Intel has realized this. Back before iAPX86 every microprocessor was an embedded controller - that's why microprocessors were developed (to replace manufacture-time programmed PLAs with software controlled logic). The 6502 was an embedded controller, the ARM was too. Intel has been driving headlong down a blind alley for 25+ very successful years, but it really *is* a blind alley. There is only so much money to be made controlling the main CPU, there is so much more money in all the other CPUs that the main CPU has to call on to do even something as simply as reading a piece of flash memory.
