HP Spectre 13.3: How thin is this?

Who doesn’t love thin laptops right? Apple started the trend. HP's Spectre 13.3, which offers top-notch performance and a reasonably good keyboard in a body that lays claim to being the “thinnest laptop in the world.” Determining a laptop’s thinness can be tricky since laptops aren’t uniform blocks, exceptions for Google Pixel C of-course. The 2015 MacBook 13’ for example, is 13mm thick at its rear, with the front lip getting down to 4mm. The Spectre 13.3 is, for the most part, 10.4mm to 10.5mm, with the back end measuring about 12mm. Given such variances, probably the best way to determine thinness is by eyeballing it.
