I remember a time when my phone was capable of just three things: Calling, texting and costing my parents $50 every time I accidently logged onto the not-yet-proficient mobile internet. Now, my phone has essentially become my wallet, which in turn has basically become a graveyard for my soon-to-be obsolete credit cards and a bunch of AMC Theaters gift cards that my aunt sends me every so often.

Soon, I expect pretty much everything in my pockets to become digitized — probably even the lint.
