New York Times:

There are a lot of approaches to getting rid of wall-warts, those blocky power transformers that let you plug your low-voltage, battery-powered USB products into the wall to charge.But this one is a little more elegant than most.Newer Technology has designed a two receptacle in-wall outlet called “Power2U” that also has two USB receptacles arranged so you can use all four simultaneously.

Clever idea but we may need vendors to start making USB cables even longer.
