The problem with your example solution is your listing one top of the line charger for one device. You can use that same Maha c9000 for a dozen different gadgets so the price gets divided between all of them as well as the pack weight.
Actually, you *need* a top of the line charger to effectively manage NiMH batteries, IMO.
as I said before, but looking at a bigger real world picture, newer technology (low self discharge nimh), ability to share the spares, and the ability to supplement with a $10 bulk pack of 30 AA's if needed the advantages of lithium ion are quickly outweighed by standard AA's
I won't bother responding to the rest since we are obviously not communicating. I've never said using AA technology wasn't flexible, etc.
