cellphone-sized X86 PC motherboard potential OpenMoko platform?

There are some things that are not true here.
True is, that x86 is on the bottom of popularity, because of the
Also it's true, that linux runs on x86. Linux's also running on SPARC - but
nobody would use SPARC in a phone, so that is simply no reason for using
But it is not true, that skype only runs on x86. There is skype for Win
Mobile devices [1] (I haven't ever seen a win mobile device using x86) which
mainly are ARM/XScale based. Skype is also working on getting their software
running on Symbian (Series60) - a platform only used on ARM.

It is also false that flash/shockwave only runs on x86. My Nokia 7710 (ARM9
based) has opera mobile with flash-plugin and it works perfectly.
The Nokia 770/N800 - also ARM based - has a flash-player as well.

So I still see no reason for having a energy comsuming x86-monster in my
phone. :)
