Everyone is ignoring the fact that by selling their Atoms for "free" Intel is keeping AMD on the edge of bankrupcy by keeping their mobile chips unsellable.
In a few years from now when mobile devices become powerful enough to handle most people's everyday tasks, the conventional desktop PC may start losing market share at an alarming rate. If Intel fails to secure a reasonable chunk of the mobile market before that happens, Intel/x86 might be screwed.
Even if Intel did decide to start making ARM-based chips to get a piece of the ARM chip market, they would have to compete against all the other $20-40 SoCs out there, which means much narrower margins than what they get on the x86 side. That would put them in a similar situation of being stuck selling chips barely above costs that AMD is in.
AMD getting hurt is merely collateral damage at this point: if Intel is failing to get good market share by almost giving their chips away, AMD would likely fare even worse with their slower and less power-efficient x86 SoCs. You could say Intel is sparing AMD the trouble of trying to warm the mobile market up to x86 chips.
