> Reducing mA (power draw) rather than increasing mAh (power storage) is the most effective way to increase battery life, which would go a long way to explain manufacturers’ obsession with thinness (which, in electrical terms often directly translates efficiency (i.e., smallness)) in their devices rather than just giving us something that endures. I think it goes the other way; the manufacturers' obsession with thinn…
I find myself thinking that i recall reading about certain thinkpads (or some other brand) had the option of an attached battery that would fit flush with the laptop bottom.

The idea of the frames being that if one replace the laptop one only need to replace the frame but continue to use the batteries.
