Microsoft appears to be gearing up to release a new, smaller version of its Windows-powered Surface tablet later this month.

The media were yesterday asked by the company "Join us for a small gathering" at 11am ET on May 20th, presided over by new Microsoft CEO Satya Nadella.

Surface Mini invite

Microsoft first introduced its Surface tablets in October 2012, with the second generation Surface 2 following a year later. The devices were Microsoft’s attempt to take on Apple in the ever-growing tablet device market, and a smaller form version of its tablet, currently available in a 10.6inch screen, would help Microsoft keep track with Apple’s iPad Mini.

Details regarding the new device are still scarce; however last month several sources claimed a Surface Mini would offer a 7.5inch display running at a 1440×1080 resolution. Other rumours state that the device will be powered by an ARM processor running Windows RT.

The device will also be marketed as a note-taking device similar to Samsung’s Galaxy Note phablets (halfway between a phone and at tablet), offering support for stylus devices with a screen specially designed for writing on.

Microsoft has not commented on this latest rumour, but the creator of the original Surface device, Panos Panay, told The Verge last year that: "We have a lot of great things that we are thinking about and working on, and there are multiple aspect ratios and sizes and awesome things to come from Surface."
