Microsoft is reportedly working on a foldable device with an emphasis on pen and digital-ink functionality that runs Windows 10, and it could be here as soon as next year. The company is looking to create a new category-defining mobile device that's aimed at an entirely new demographic, and that puts pen and digital inking at the forefront of the experience. Windows Central reports: At Windows Central, we've been covering two ongoing internal projects within Microsoft: CShell and Windows Core OS. Both of these projects play an important part in Microsoft's next rumored mobile device, which appears to be commonly referred to as "Andromeda" on the web. According to our sources, the Andromeda device is prototype hardware; a foldable tablet that runs Windows 10 built with Windows Core OS, along with CShell to take advantage of its foldable display. I imagine CShell plays an important roll in the foldable aspect of this device. Considering it's foldable, being a tablet doesn't mean much, and I'm told it's designed to be pocketable when folded, kind of like a phone. I make the comparison to a phone because I'm also hearing that it also has telephony capabilities, meaning you could replace your actual smartphone with it and still be able to take calls and texts. My sources make it clear, however, that this is not supposed to be a smartphone replacement but rather a device similar to the canceled "Microsoft Courier." In short, Andromeda is a digital pocket notebook.
