When John F. Kennedy was assassinated in 1963, the Zapruder film provided investigators with key evidence of the shooting.

Imagine you go to the doctor's office, and instead of being handed a clipboard with the usual paperwork, they hand you a tablet. You fill in all of the information digitally and send it via the tablet to their office database. Then, with that same tablet, you have a list of digital magazines to browse instead of making a trip to the magazine stand. Suddenly, the paper trail you used to leave during your doctor's visit has been made completely digital. With new app technology, this could become the norm in many business settings.
