The very sturdy Dell Latitude XT3 is an enterprise-class laptop that comes with a twist: You can quickly fold it into a tablet PC by rotating its screen on its single central hinge. Such so-called convertible PCs often land in large organizations, including those in the health care, education, and law enforcement fields. This kind of machine needs to perform well both as a laptop and as a tablet, hold up well in hectic environments, and deliver good battery life. For the most part, Dell's third-generation Latitude XT fits the bill nicely.
The hefty but attractive midlevel model I tested sells for an equally hefty $3003 (as of April 12, 2012). The moment I picked up the XT3, I knew that it was made to take some knocks. The case is constructed of thick, stiff plastic with magnesium-alloy reinforced corners. I found almost no flex in the PC case or the display panel. Dell claims that it made the XT3 spill-resistant; I didn’t test that, but the thin rubber gaskets that line the keyboard, the screen bezel, and the perimeter of the computer’s top panel are reassuring.
