Now that I have a supercomputer in my pocket (currently a Google Nexus 5), life is less cluttered. I no longer need to carry:

  • paper
  • pen
  • flashlight

Travel with:

  • maps
  • GPS
  • laptop

Own:

  • calculator
  • camera
  • video recorder
  • Gameboy
  • dictionary
  • encyclopedia
  • MP3 player
  • watch
  • pager
  • alarm clock
  • level
  • barcode scanner
  • calendar
  • day planner

Memorize:

  • addresses
  • phone numbers
  • social security numbers
  • license plate numbers
  • birthdays
  • credit card numbers
  • first aid

It could replace:

  • TV
  • books

…although I still own a TV and shelves of books.

I expect it will eventually replace:

  • keys
  • wallet
