In my house, I am hard up for AC outlets. I have them all filled with digital picture frames and home theater gear in the living room and in the office I have too many computers plugged in to find an outlet most days.
A new concept wall outlet would make it easier for me to get a plug to charge my iPad and iPhone. The concept outlet is very simple and just adds a couple of USB ports to the normal AC outlet.
I would like to see this concept become a feature in homes here in the US. That would certainly make it easier for me to get all my hardware plugged in and still be able to charge my iPad since the USB outlet on my PC lacks the needed amps for my iPad.
