Microsoft's first tablet computer, introduced at the end of 2012. The Surface originally came in two forms: ARM-based tablets that ran the Windows RT operating system (no future versions), and x86-based tablets that run Windows 8 and up (see below). In 2015, Microsoft introduced a combo tablet/laptop Surface (see Surface Book) and a year later an all-in-one desktop model (see Surface Studio). See Windows RT and Windows 8. Not the First Hardware for Microsoft Although known for software, Microsoft has also been successful with mice, keyboards and the Xbox game console. For more than 30 years, Microsoft depended on third-party PC vendors for Windows hardware until it introduced the Surface. See also PixelSense.
