Finally, something that actually looks like the next big thing.

Wireless gadget charging.
This might not be the sexiest thing in the world, but that inventions with the greatest impact rarely are. I think being able to replace your chargers with a simple contact pad is genius. Imagine contact pad outlets, contact pad power for laptops, and so on. No more tripping on cords, no more plugging things in.

It ain't world hunger, but then again, neither is/was the iPhone.
