You know what would be kind of neat? If you could triple-tap any word on the iPhone, and get a dictionary definition of it.

And then you could quadruple-tap to copy it to the clipboard. And quintuple-tape to hear it pronounced. And sextuple-tap to set that pronunciation as your ringtone. And septimple-tap to see the word spelled out by divers arranging themselves in a pool beneath a downward-looking camera. An octopple-tap to have it do something octopus-related.
