DreamPlug: A PC that looks like a battery charger

Many a times you need a computer just for basic rudimentary computing tasks in places with limited power and space, why use a computer which consumes a whole lot of power while you can just do the same task with a PC which uses only a small amount of power and hardly takes up any space? The solution to the problem is being answered by the ultra small PCs which have been coming up in the market in recent times called plug computers. One recent device that has come up is "DreamPlug" from Globalscale Technologies, which fits into a power plug, no power cord needed.
