HP goes against the grain at the MWC 2015 as the company launches Spectre X360, its brand new convertible Ultrabook.

With a start time of just four seconds, HP's Spectre X360 is probably boots faster than any other Windows PC. Designed to be used mainly as a laptop, the Spectre X360 can also be converted into a tablet by flipping the screen backwards.

According to ComputerWorld, HP's Spectre X360 may not feel like the lightest and thinnest hybrid, but it definitely performs quiet well and boasts an array of features. ARSTechnica noted that the Spectre X360 is a new convertible Ultrabook that serves as HP's answer to both Lenovo's Yoga line as well as Dell's most recent XPS 13.

This fold-back design style of laptop/tablet hybrid gained popularity among users as it does not compromise the aboriginal clamshell laptop experience. It is said that this is also comparatively less complex mechanically. In addition, laptop/tablet hybrids are cheaper to produce as opposed to overly fidgety pull-apart or sliding-screen hybrids.

According to ComputerWorld, the hybrid will ship worldwide this month (March) starting at $899.

Its hinge opens a full 360 degree until the back of the lid is pressed against the bottom of the base. This facilitates presentation-friendly "tent" and "stand" modes to the laptop and a watching-movie-in-bed-friendly tablet mode. Just like in Yoga, the keyboard on the back, in addition to the general size and weight of a 13-inch notebook, makes it a poor general-purpose tablet, according to ARSTechnica.

That said, although these modes work fine, the Spectre works best when used as a laptop. Further comparing the Spectre with even the top-end Yoga, which is predominantly made of plastic, the X360 is all aluminum. The chassis, though thin, it's still very solid. The X360 is housed in a 15.9mm thick and 3.3 pounds aluminum body, it's not the smallest or lightest 13.3-inch laptop available; nevertheless it's competitive with most of the other Haswell and Broadwell Ultrabooks available.

CNet noted that HP jumps into Intel's fifth-gen of Core i-series CPUs, offering Core i5 and Core i7 models. The X360 sports a backlit keyboard similar in style to HP's various brands, with a sunken keyboard tray, widely space island-style keys and rounded corners on the four edge keys.

The Spectre X360 will be available direct from HP starting March 1, and in Best Buy stores from March 15.
