Engineered to endure spills and tumbles with rubberised edges and rounded corners for minimal drop impact, a spill-resistant keyboard and captive keys. Rigorously tested to withstand 30-inch drops onto steel, 48-inch drops onto plywood, thousands of 4-inch micro-drops, and tens of thousands of hinge cycles. The new Latitude 3140 has been tested more rigorously than ever for maximum endurance.
