Indeed, devices like the iPhone and the OpenMoko Freerunner demonstrate
that you can build pretty sweet devices and user-experiences around
400~600 MHz ARM processors.
Having said that this is still a very hypothetical discussion because
we're not going to see anything resembling what we today know as
desktop- and full-internet-experience on ARM CPUs. That's at least 6 to
12 months in terms of the hardware and god-knows-how-many-years away in
terms of the software.
I strongly believe that for the foreseeable future low-power x86 is the
way to go, and if it's only for the simple reason that people are very
unlikely to make the (definitely worthy!) performance-improvements that
Tomeu is mentioning because it's more sexy to work on the next funky
iPhone or Compiz Fusion effect.
Just my 2 euro-cents,
