Caterpillar's B15 Smartphone
CAT's B15 smartphone, made by the same company that manufactures bulldozers, promises to be tough as nails and smart too. Dustproof, waterproof and impact resistant, this phone features a rubberized casing with few openings, a 4-inch scratchproof Gorilla glass screen and an Android 4.1 Jelly Bean OS. It tracks finger motions even when the screen is wet and, according to the company's site, will bounce back from an almost 6-foot drop on concrete. Priced around $350, CAT also offers two lesser models starting at $130, but it isn't compatible with CDMA carriers like Verizon or Sprint.
