Here is yet another one that actually makes you give up a 120V outlet
for 2 USBs.

I would think a much better idea would be to design table lamps with a
couple of outlets in the base.

I think they could add an mp3 player to your microwave for music in
the kitchen and another two places to charge your phone for a couple
of bucks.
