The HP Spectre x360 13 unites features that seem impossible at first glance: it is thinner than a USB port but is equipped with USB connectivity. It is small but has a 4K OLED display that takes up 90 per cent of the screen area. In the narrow bezel surrounding the screen, a 2.2 mm webcam with face recognition is integrated. The chassis is made of double anodised aluminium with polished edges that lend it an elegant appearance.
