You don’t need me to tell you that the smartphone is an amazing little piece of technology. It’s a web browser, camera, voice recorder, calendar and to-do list. With a few basic apps, you can read a book, find out what the president is tweeting (come on, you know you’re curious!), look at what your best friend from high school made for dinner, hail an Uber, and check the count on Tom Brady’s Super Bowl rings. Shopping, tweeting, texting.
