Although ARM is improving, I still believe it's dying a slow death. Everyone knows that Intel and AMD have monopolized the CPU patent world.

Also regarding nanometers, ARM design always seems to be one step behind.
Cortex A8 has 45 (so does my core 2 duo but it's anything but new) while i7 is built on 32 nanometers and the technology for 20 nanometers has already been announced.
The fewer the nanometers, the lower the power usage.

Also this would be a great step for cross platform applications and we could install the same .rpm on our PC as in our mobile device.

IMHO this is the future, I can only hope Intel and nokia will make it happen a lot faster
