A 2-in-1 PC, also known as a 2-in-1 tablet, 2-in-1 laptop, 2-in-1 detachable,laplet, or simply 2-in-1, is a portable computer that shares characteristics of both tablets and laptops. Before the emergence of 2-in-1s, the terms convertible and hybrid were already in use by technology journalists. The term convertible typically referred to 2-in-1 PCs that featured some type of keyboard concealment mechanism that allowed the keyboard to be slid or rotated behind the back of the chassis, while the term hybrid typically referred to devices that featured a hot-pluggable complimentary keyboard.
Both convertibles and hybrids are crossover devices, combining features of both a tablet and a laptop. However, the 2-in-1 is a sibling class of both these categories, dubbed the 2-in-1 convertible or 2-in-1 detachable respectively, distinct from other convertibles and hybrids due to the presence of features found in traditional laptop computers.
2-in-1 PCs, consisting of portable PC components within light and thin chassis, are examples of technological convergence. The devices are convenient for media consumption and non-intensive tasks in tablet mode yet well-suited to content production in laptop mode.
2-in-1 convertibles are tablets with the ability to rotate, fold, or slide the keyboard behind the display. On most devices, the hinge is situated at the display and keyboard junction. However, the Dell XPS Duo is unique in that the display sits in a frame that allows the screen to be spun.
2-in-1 detachables are devices with detachable keyboards. In most cases, the keyboard part provides few, if any, additional features (most often a touchpad, as in the HP Spectre x2). However, the keyboards of some detachables provide additional features similar to those of a docking station such as additional I/O-ports and supplementary batteries. For instance, the Surface Book can leverage the discrete GPU in the keyboard upon the keyboard's connection.
When connected to the keyboard, the display of the detachable can either be free-standing on the hinge or require external support, often in the form of a kickstand. Novel ways of providing external support include the bending frame and locking mechanism of the HP Spectre x2.
