Coming quickly on the heels of new MacBook Pros, Dell has formally launched the XPS 14z. Its system is conspicuously targeted at Apple's 13-inch notebook and uses LG's Shuriken panel tech to get a 14-inch, 1366x768 screen into the size of a 13-inch design. Unlike the exaggeration of the XPS 15z, the 14z is genuinely thinner at exactly 0.9 inches and lighter at 4.36 pounds.
