1. Decide If You Want a 2-in-1 Many PC laptops fall into the category of 2-in-1s, hybrid devices that can switch between traditional clamshell mode, tablet mode and other positions in between such as a tent or stand modes. 2-in-1s generally come in two different styles: detachable with screens that come off the keyboard entirely and flexible laptops with hinges that bend back 360 degrees to change modes. Most of these systems are much better at serving one purpose than the other, with bend-backs being laptops first and detachable offering a superior tablet experience.
