TI has just started to roll out cortexA8 based chips iirc, and in a years time we are probably looking at A9. and im not sure if its intel thats the biggest issue when it comes to low watt x86. via launched what appeared to be a impressive design recently....
And keep in mind that N800 is compatible enough with the N810 that support for the latter means de facto support for the former.
So are you ruling out the possibility of an N810-only upgrade (perhaps due to licensing rather than technical issues) at some point? Or does that de facto merely represent acknowledgement of the obvious glee with which N800 users would pirate any such upgrade?
How does Intel Atom stack up? "The chips have a thermal design power (TDP) specification in 0.6-2.5 watt range and scale to 1.8GHz speeds depending on customer need."
A quick Google search shows that a 500MHz ARM11 consumes about 0.1W on the average. "TDP" specification refers to the maximum amount of power dissipated by the device. In other words, your Atom CPU will consume no less than 0.6..2.5W (depending on the computational load).
Also notice that OMAP2 chips are produced using 90nm technology while Atom will probably start at 65nm and then go to 45nm. If TI goes up the technology ladder, its OMAP CPUs will consume even less power.
