If that hinge mechanism looks familiar, that's because it's very similar to the one found on the popular line of Yoga laptops from Lenovo, as well as me-too models from Dell and others. The idea of the 360-degree hinge is that you can use the system as a traditional laptop, then bend the lid backward, stopping at a kiosk or table tent form in the middle, or else folding it all the way back into a tablet shape.
HP Pavilion x360: A Yoga-like convertible laptop (hands-on pictures) See full gallery
Like the Yoga line, you still have the keyboard and touch pad exposed in tablet mode, deactivated, but under your fingers.
HP's pitch for the Pavilion x360 is a little different than Lenovo's for the high-end, premium-priced Yoga, which starts at around $1,000. Instead, HP's version starts at $399, which means it runs Intel Pentium chips, rather than the more mainstream Core i-series CPUs (although that's honestly fine for an 11-inch laptop).
HP says the x360 is aimed at millennials looking for a single device for work and play, and one goal for this system was to produce an affordable convertible that's accessible to anyone.
The system weighs around 3 pounds and is 21.9 millimeters thick. It features the same Beats Audio technology as the rest of HP's consumer laptop line, up to 8GB of RAM, and a 500GB hybrid hard drive. There are three USB ports, as well as 802.11n Wi-Fi and Bluetooth.
The Pavilion x360 will be available starting February 26, initially in red, later in smoked silver, both with a soft-touch finish and brushed-metal wrist rest.
