That's where there needs to be a concerted push to develop more efficient
CPUs and memory, in the engineering sense of efficiency (i.e. better
power consumption, not speed). In desktop and server class machines,
increasing speed has generated more and more waste heat, to the point
where Google likes to build its server farms next to rivers to reduce
their air conditioning costs. You can't afford to do that on a battery.
Even for desktops and servers, I'd prefer to give up, say, 80% of future
speed gains for a 50% reduction in my electricity bill.
