The smartphone era has lightened our loads. Instead of packing our purses or pockets with a Walgreens store's worth of necessary items, we've now got phones that have it all. Things we'd never leave home without are dwindling to a precious few.
Here's a quick look at 20 things we no longer need to lug around.
Maps: Forget folding that unwieldy piece of paper.
Grocery list: Update it from home while your spouse is still at the store.
Checkbook: Apps like PayPal make paying bills a breeze.
Calculator: Use your phone to figure the tip.
Books: You've got an entire library in your pocket.
Handheld video games: Remember when the Game Boy seemed tiny?
