It lets you take selfies like a pro and share with your circle of fans, friends or embarrassing family members. It lets you text things you may or may not later regret with the greatest of ease. It lets you stand your phone up on an airplane tray table to watch a movie. When you?re done, it collapses flat like your bangs in a rainstorm.
