Don't forget that small CPUs are becoming desired in computers, too. Laptops have been fitted with smaller CPUs for years and the trend toward miniaturization moved to a new level with netbooks and ultrabooks.
One fascinating thing about that trend is that we almost expect things to be disposable. CPU won't cut it anymore? Just toss out your old computer and get a new one. Swapping out CPUs was fairly common on desktop computers, but that kind of thing was impractical with laptops and that has spread to smaller devices.
