Dell's second generation fully rugged laptop, the Latitude E6400 XFR, arrives with an Intel Core 2 Duo processor with vPro technology, a state-of-the-art CPU that's uncommon in rugged computers. In addition to the latest Intel processor, the E6400 XFR has a powerful NVIDIA Quadro graphics card and a 120GB hard drive or optional solid state drive ($100 extra). The case is made of a non-metallic material used in missiles and aircraft. Called "Ballistic Armor" by Dell, this material won't stop a bullet, but it does provide exceptional protection from impact and from water and dust. The Latitude E6400 XFR is MIL-STD-810F compliant.
