The new ATOMS are getting better, but yes the ARM is still a bit better power wise.

That said, first chance i get i will get one of the UMID's (<6" Laptops running x86), i like arm but i would just love to have a mini x86 system, this is what im used to, for with WIN for 15+years and not linux.

One thing that could be very nice/funny would to have a NEW Motherboard designed for our N900, but this time with the newest and best power efficient ATOM CPU, it should be quick to have drivers and such running, it only needs to have drivers for screen and touchscreen, everything else is on the board, still it has to have all the stuff, IR, FM TX/RX.
