Microsoft has been working on a new Surface for at least two years. Codenamed Andromeda is a device that has been featured on patents, reports, and operating systems several times and designs two screens. According to the Microsoft internal document from The Verge, it also has a flexible Surface device in its pocket.
Microsoft describes the Andromeda project as something that has been quietly incubated by the company, and calls it a "new and fatal" device to influence the overall Surface map and to blur the "computer" and "mobile" creates "This is a new retail pure factor factor that collects innovative, new hardware and software experiences to create a personal and versatile PC experience." Thurrott actually posted some of Microsoft's plans early this month, and Numerama first released the Andromeda code last year. Microsoft has refused to comment on The Verge from Andromeda.
