This may be a nit, but, you will _NEVER_ see AC power at any, let alone all of the seats. Seat power that works with the iGo system is DC and is not conventional 110 AC.
Arnic 628 is a 16 volt dc, maximum 100 watts per seat, dc conversion to 15 volts (aircraft power bus is 400hz 110volt ac) and from 15 to whatever your laptop requires put the effective power limit at about 75 watts The approach of the airlines and the faa is to limit the number of outlets and their variety based on the load that the system can support. most in-service aircraft simply aren't generating enough power to deliver it to every seat in the plane.

And this was BOS -> MUC, which ain't a short flight.It's quite likely that on a grander scale of things, it's better economy that the few people who want to use their laptop the whole flight, do get two batteries, than doing the investment of putting AC power in all seats. Otoh, more batteries on planes increases the risk of fire due to exploding batteries happening in the plane :P --Mikael Abrahamsson email: swmike () swm pp se
