Supreme technology crafted to withstand Mother Nature's worst moods, the Earl Backcountry Survival Tablet fuses Android 4.1 with an E-Ink screen and the latest in GPS wizardry. Further features include weather tracking, location and route information, a radio tuner, walkie-talkie, emergency lighting and text and voice message capabilities. It's Bluetooth enabled, can be used while wearing gloves, is water, dust, shock and mud proof and will even work at an altitude of 40,000 feet. We're not really too sure why, as even Mount Everest isn't that high, but it sure does prove a point.
