I don't disagree with your point, except this:

Just the slow-down for the rest of the market alone (Atom isn't anywhere close to ARM in terms of functionality/watt), it might be worth it.

ARM licencees already have next-gen (Cortex-A9; ie: Tegra-2 etc) chips coming this year. Any slow down in new designs from ARM won't effect the market for a couple of years as these chips are much faster than the current designs (Cortex-A8; ie: Snapdragon, TI OMAP 3000, Apple A4)
