Microsoft has just unveiled a whole new category of device designed to showcase Windows 10. It’s called the Surface Hub. As the next evolution of the company’s Perceptive Pixel project, Surface Hub features an 84-inch 4K display with support for multi-touch and pen input. A 55-inch option will also be available, according to a press release. The massive screen also includes dual cameras, microphones, and a wide array of “advanced sensors,” Microsoft says, though it’s not yet sharing full details on all that’s inside Surface Hub. We’re also left clueless as to how much it will cost.

It’s a Windows 10 device, but obviously strays far from your typical desktop or tablet experience. Microsoft has customized the Windows interface for such a monstrous display, offering quick access to Skype video calls, a OneNote whiteboard for drawing and annotation, and a shortcut for connecting to another nearby Windows 10 device. Signature Windows features like Snap remain, however. And you can use just about any app on the big screen.
