Most of today’s laptops are plenty portable. But HP’s latest offering proves that PC manufacturers are still finding ways to make their devices thinner and lighter still.

HP claims that its Spectre laptop, unveiled April 5, is the world’s thinnest laptop.

The Spectre measures 10.4 millimeters (0.41 inches) thick. This would mean that it’s slimmer than than the 12-inch MacBook (0.52 inches), MacBook Air (0.68 inches) and Dell XPS 13 (0.59 inches) at their thickest points. It’s also thinner than the 0.52-inch Razer Blade Stealth.

HP’s new notebook looks like a sleek, general purpose laptop, with an advertised nine-hour battery life, 13-inch HD 1920 x 1080 resolution display, and sixth generation Intel Core i5 or i7 processor. That last bit is particularly notable, as many super-thin laptops run on Intel’s Core M processors, optimized for mobile performance rather than desktop-like power.

The Spectre doesn’t come with any hybrid features like similar offerings from other companies, some of which include screens that can detach from their keyboards or twist and turn to function like a tablet. But the Spectre’s simplicity and premium design make it a potential competitor to Apple’s MacBook Air.

The Spectre will be available for pre-order on April 25 for $1,169.99 before it hits Best Buy stores on May 22 for $1,249.99.
