Our mobile devices have long since evolved from portable telephones. Especially for people in the younger demographic like me (I'm in college), my colleagues can (and do) live off their phones. They send and receive email, communicate socially via Facebook, Instagram, and Twitter, play games, takes notes, and compile to-dos and calendar appointments. It's quick, efficient, and painless.

Before you know it, our phones will soon be replacing our credit cards (i.e. wallets) and opening doors for us (i.e. our keys). Mobile phones are arguably one of the most important things we carry around with us in our daily life, and it won't be going away anytime soon. And whoever innovates fastest to add more value to our lives, wins.
