#mobile devices.

In the future, I envision wildly more modular and customizable phones. Perhaps in addition to our own beautifully-designed phones, we could sell some kind of phone template, and entrepreneurs the world over could build a local business on building phones precisely tailored to the needs of his or her local community. You want a waterproof, glow-in-the-dark phone with a bottle-opener and a solar charger? Someone can build it for you—or you can print it yourself!
