Don't expect to find revolutionary changes with the new HP Spectre x360 13. The latest version of this venerable laptop—it dates to HP's acquisition of VoodooPC in 2009—continues the company's tradition of steadily improving a fine machine.
The competition requires it. You could argue that VoodooPC, a company that enjoyed a reputation for packing high-end performance into the slimmest possible package, kicked off the whole ultrabook movement. Buyers looking for such a rig today can choose from any number of machines, including the sweet Lenovo Thinkpad X1 Carbon and Dell XPS 13. Like the Spectre, they cater to mobile power users by offering solid benchmarks in svelte packages that weigh less than 3 pounds.
HP has once again revamped the Spectre x360 to stay above the fray. It upped the build quality (the chassis is machined aluminum), reduced the width by nearly two centimeters, and enhanced the color depth of the 13.3-inch touchscreen—which now sports a resolution of 3840 x 2160 pixels in resolution. Speakers, once located only on the bottom of the unit, now include a pair firing upward and another pair firing downward. The audio sounds great whether you’re using it in standard laptop mode or in tablet mode.
