And what about the mainboard? 
Recently read that an old 1GHz Athlon with an old K8 mainboard is faster and uses less power than an Atom with its board

display backlights (i hear nokia plans to go amoled, something for the N900?), storage, radios, they all draw more now then the cpu.

But that's something Intel has to face as well.
Going up with speed is something that is proven to be the wrong answer.
Personally I'm skeptic about the extremely high number of general purpose cores as well.

The TI calculator emulator is a bit slow on my n810, but I expect omap3 to deal with it much better. And that would emulate an entire 68K based system.

Anyway, it would be quite interesting to investigate (if it's not done already) what is the main performance bottleneck in arm->x86 emulators and if any reasonably simple extension to the arm instruction set can result in more efficient x86 emulation
