1) A foldable, wallet sized umbrella.

2) An e-ink kindle the size of your cell phone. For reading on the go, without killing battery life or your eyesight.

3) A folding cell phone. Super thin. So small you can keep it in your wallet. Unfold it once, and it’s a standard sized 5 inch cell phone. Unfold it again, and it’s a tablet.

4) (stolen from Josh) A pocket sized 3d printer.

5) A pocket sized air conditioner. I don’t just mean a fan circulating air. A full blown air cooler.

… This category was a lot harder than I thought…
