A desktop computer, a desktop PC, or a tabletop is a class of devices in a large-screen, all-in-one portable computer with an internal battery. It can either be used on the top of a table, hence the name, or worn around the house. Desktop computers have a multi-touch screen of 18 inches or more, a battery capable of performing at least 2 hours of stand-alone work and a full desktop operating system, such as Windows 10. They typically come with user-activated touch-sensitive games and apps, and typically marketed as home entertainment devices.
Manufacturers of some desktop computers provide a specialized graphical user interface to simplify the simultaneous interaction of multiple users, such as the Aura interface installed on the Lenovo IdeaCentre Horizon tablet. A number of manufacturers have released their own tabletop versions, some important examples are HP Envy Rove 20, Dell XPS 18 and Sony VAIO Tap 20.
