HP claims that although this is the thinnest and lightest 15-inch convertible (15.9 mm thick and 4 pounds), the battery will still last up to 9.5 hours with the 4K display or 13 hours with a lower-res 1080p panel. That would be impressive, if true — we'll have to get one soon to test.
Additionally, the company recently refreshed the older 13-inch model with Intel's latest Core processors, and now it will also offer an OLED screen option — the first for any convertible, HP says. Go with this option and you'll get a 103 percent color gamut versus a 72 percent one. The contrast should be noticeably deeper too. And, because OLED panels are thinner, the machine will weigh 50 grams (or 0.11 pounds) less than it would otherwise.
On the much lower end, the company unveiled a bigger version of its Pavilion x2 tablet hybrid. The new model has a 12.1-inch screen, up from 10.1, with an included keyboard that attaches magnetically instead of with a latch mechanism. As on other HP two-in-ones, like the Spectre x2 we recently reviewed, the keyboard appears comfortable, with 1.5 millimeters of travel. Also like the Spectre, though, the keyboard adds a good deal of weight: The tablet alone is 1.6 pounds, but that balloons to 3.23 pounds with the dock. Under the hood, the specs are, as we said, fairly low- to mid-range: You get a 1080p display, with Atom processors to start and Intel's Core M chips in the highest-end models.
