Imagine you're tailgating before a big football game, checking scores on your phone. You reach into the cooler for a beer, only to realize that the bottles are not twist-offs. At this point, you could drop to your knees, shake your fists at the sky, and curse the evil that would bring such a wicked fate upon you. Or you could just turn over your phone and pop the bottle open.

The innovators at HeadCase had such situations in mind when they created a line of cases with built-in bottle openers—only one of several stylish but practical products designed to enhance the use of mobile gadgets. Along with custom photos, cases sport camouflage designs and the colors and logos of professional and college teams. HeadCase products protect devices from both Samsung and Apple, meaning that users don't have to settle for the brand of smartphone they happened to be holding when they were born.
