Dell's XPS line is one of the most venerable in computing. It dates to 1993, and even now continues pushing high-end computing performance in a (reasonably) portable platform.
While the XPS 15 Touch has the now-standard ten-point touchscreen, it's first and foremost a straight-up laptop that eschews tablet frivolities in favor of raw power and solid usability.
With a sixth generation, 2.6GHz Core i7 CPU, 16GB of RAM, 512GB solid state drive, and graphics from the latest Nvidia GeForce GTX 960M, the machine is as state of the art as things get. But the display surely is the centerpiece, a 15.6-inch LCD with 3840 x 2160-pixel resolution. It's one of the best on the market, with dazzling brightness and clarity. Dell it the Infinity Edge display, owing to the tiny border between the screen and case. Just a couple millimeters thick, Dell says this innovation lets it wedge a 15.6-inch laptop into "a form closer to a 14-inch laptop."
That may be technically true, but this is still a big computer. The XPS 15 starts at less than 4 pounds, but my review unit was a full 4.5 pounds, right in line with other 15-inchers available today. The device certainly feels hefty—particularly in an era of 2- to 3-pound competitors—and at 23mm thick, it actually has a bit more girth than many of its competitors.
None of that matters much, as the XPS 15 is amply portable yet designed with performance foremost in mind. On this front, it delivers, turning in stellar performance numbers on a wide battery of tests, from general applications to high-end graphics benchmarks and gaming runs. If there's one weakness here, it's likely the SSD, which is on the slow side for a machine that otherwise pushes its tech to the limit. At a bit under 4 hours of full-screen video playback, battery life is about average for this class of machines.
