Announced yesterday at MWC 2015 was the HP Spectre x360, the latest in HP's line of high-end high-design Spectre portables. The previous Spectres have been very nice machines, but the x360 might just take the cake.

The Spectre x360 sports, as the name might imply, a 360° hinge mechanism that allows you to pivot the screen all the way around and close it onto the backside to use it as a tablet — a tablet that just so happens to have a 13.3-inch display (in 1080p or QHD) and a high-powered Intel Core i-series processor.

This is, of course, not even remotely the first convertible Windows laptop we've seen with a display that swings all the way around, but it is certainly one of the nicest. That comes down the the body, which was machined out of aluminum with crisp corners, lightly-polished sides, and measures just 15.9mm thick and weighs 3.3 pounds. Even with the Core i7 processor pushing 3.6 million pixels on that QHD display, HP still rates the Spectre x360 for up to 12.5 hours of battery life.

But let's just talk about the hinges. In lieu of a traditional friction hinge, HP's opted for a gear-driven hinge that they claim stands up to long-term repeated wear better than a friction hinge. These gears are encased inside a polished silver shell, adding a bit of bling to the otherwise understated design.

We will, of course, need to spend some quality time with this Windows 8.1 machine before we can give any conclusive judgements. But in our brief time with the HP Spectre x360 we came away impressed. Regardless of how things shake out, this is just beautiful and solid piece of design.

The HP Spectre x360 is up for order now on and projected to ship starting March 15, priced from $899.99 to $1149.99, depending on which options boxes you tick.
