Getac's B300 rugged laptop first debuted in 2008, but the fourth-generation version was released early last year and operates on Windows 7 Professional. The latest B300 features an Intel Core i5 or i7 processor that allows it to perform 67 percent faster than previous models, new Intel HD graphics, built-in 4G LTE and Wi-Fi access, and increased power efficiency that gives it one of the longest battery lives on the market -- lasting up to a total of 30 hours with dual batteries. Its sealed design and waterproof keyboard protect against dust and liquids, while the magnesium alloy it contains protects against drops and vibrations in temperatures up to 140 degrees Fahrenheit. The new 13-inch QuadraClear display allows for readability in the sun, as well as an optional touchscreen or night vision display, and it features an integrated carry handle for easy transportation. Getac's latest version prices around $3,200, according to Notebook Review.
