The old saying that computing is now ubiquitous (it makes me cringe when ever I read that over-used phrase) isn't really quite true. Try taking a standard PC or notebook on a boat, 4WD trip, camping, dirty factory - anywhere where there is the risk of exposure to the elements, and you'll find that computers can be quite restricted. Trident have just the solution: "The MMB Mobile PC from Trident is powered by an energy efficient, cool running VIA C7 1 GHz processor, eliminating the need for fans and vents. The MMB Mobile is sealed to IP65 on all but one side where the connections are placed. An optional 1 inch skirt provides further protection once fitted." Source: ElectronicsWeekly.com.
