Engineered to endure spills and tumbles with rubberized edges and rounded corners for minimal drop impact, a spill-resistant keyboard and captive keys. Rigorously tested to withstand 76.2cm (30) drops onto steel, 121.92cm (48) drops onto plywood, thousands of 10.16cm (4) micro-drops, and tens of thousands of hinge cycles. The new Latitude 3120 has been tested more rigorously than ever for maximum endurance.
