Infographic: everyday things we've replaced with smartphones

Cellphones, or dumbphones, have been eclipsed with smartphones, but what about everyday items like mp3 players and encyclopedias? Most likely, you’ve not purchased either since you got your shiny new smartphone.

In fact, you can trace the decline of encyclopedias with smartphone sales very easily in the eBay infographics below. The trend is also similar for MP3 players, atlases, digital cameras, and more. Estimates place these combined items around  $11,000 per consumer while an average phone costs $200-$300.
