Why do people need computers, really? A smart phone is a small portable computer with a phone built in. Maps is one of the types of apps that most people use but it's not the only one. Email, social media, text messaging, note taking, audio and video recording, a camera, a compass, pedometer, access to cloud file storage, reading apps like nook or kindle are a few of the apps that I use regularly on my phone in places where a laptop or even a tablet wouldn't be inconvenient or impossible.
