The picture to the right shows how tablets are being used in naval applications where ruggedness, waterproofing, display performance, and the ability to hold up in extremely demanding environments matter. This Intel Atom-powered 8.9-inch Samwell Ruggedbook SR820 is installed on the sail boat of a notable Italian ocean navigator. We had the 2.9-pound SR820 in our lab a while ago and called it the tablet equivalent of a rugged netbook computer (see our SR820 report).
