Drops, shocks, heavy vibrations, dust, water and temperatures in the extremes -- just the kind of punishment you'd expect a DRS Armor slab to put up with, and the firm's latest do so without thebriefcase-like look. With MIL-STD 810G certification and an IP65 rating, the 7-inch multi-touch slates can withstand some rough and tumble -- though there's no word if they can pass the tesla coil benchmark. At 1.3 pounds, the Android 3.2-loaded X7ad squeezes out eight hours of battery life with a 1GHz dual core Tegra 2 processor. Its Windows-minded doppelganger, the X7et, holds a six-hour charge, sports an Atom Z670 processor and tips the scales at just under 1.5 pounds. If the chunkier look strikes your fancy, the 12.1 inch X12kb has you covered -- though at 5.5 pounds, it's the lightest MIL-STD-810G certified convertible tablet currently available. The swivel screened slate has up to eight hours of battery life, a Core i5 560UMCPU processor, a polarized LCD glass display, a spillproof keyboard and touchpad in addition to a one-click stealth mode that disables light and sound for "covert operations." With GPS, WiFi and Gobi Wireless Broadband options, all three of these are ready for missions at home and abroad, however you might need that stealth function to find out the (currently unspecified) pricing.
