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
