Well, at least give Intel props for coming up with a better solar power regulator. It's the kind of tech that can raise tolerances for the kinds of solar cells one can use and can potentially reduce the rollout costs as a result. May not be enough to take us breakeven, but I still call it a step in the right direction.
As for low-power PCs, that's becoming more a plus these days. But it does raise some questions, such as, "What about research into sweet-spot computing that can both crank out serious performance while still avoiding excessive power draw?" Now, I understand physics puts a hard limit, but I personally wonder how close we are to the theoretical limitations of an optimal power/performance ratio.
