From my perspective, this one is a bad idea. My last two trips, involving seven different airports, tells me that the folks with no consideration for others who run power cords across aisles and block seats with their toys already have enough outlets with which to public menaces. In a crowded gate area, there are plenty of hazards without having to deal with power cords stretched here and there to trip you. Either plan ahead or get a car charger, the gate areas are not offices.

One improvement I'd like to see on the plane is to make the seatback pocket from mesh instead of opaque fabric fabric: that way you could see what is in it before you reach in for the safety card and encounter somebody else's used Kleenex. See-thru mesh pockets should also make it easier for the cleaning crews to see trash they need to pull, and hopefully they would make it harder for pax to leav things behind in the pockets because they'd be able to see at a glance they had left something behind. My brother would benefit greatly from such a change - he is notorious for leaving his return tickets in the seatback pockets.
