I totally agree that next year some of the new homes, cafes and hotels will have this extra power plug installed somewhere in the walls of their crib. I love this concept to add USB power plugs in my home and since most of us here are using mobile devices to charge and kinda sucks sometimes to stock lots of power chargers in one corner to charge all our gadgets, so the use of USB chargers will be a good idea and we can stock only 1 or 2 cables in our charging area.
I' m going to research more and study on how I can install one in our study room and kitchen.
I saw this info from PC World's 2012 Gadget preview for CES 2012
