#15 The thing senses hand gestures above it
Imagine you've just sat yourself down to a wonderful, messy, sticky plate of ribs, and you want to read the latest post by our very own Jason Perlow. If you had an iPhone, you'd have to slather the screen with sticky sauce to scroll the page.
On the other hand, since my new Android phone senses gestures without requiring physical contact, if you had your own Galaxy S4, you'd be able to simply wave your hand (without touching the device) and still be able to control it.
See? Now you can have your ribs and read it, too!
