4 things your phone could replace that you probably still carry

For the last 10 years, the cell phone has been the most technologically evolving piece of equipment we all own. I still remember when the coolest thing my phone could do was play Brick Breaker, and now, I can use it for things that I once thought were silly or made up.

It was stuffed with everything from a mountain of business cards to cash, credit cards, and more. It was uncomfortable and actually started to cause some issues with my back.
