HP reveals Sprout: A ‘blended reality’ Windows 8 PC with 3D scanning and a projected second screen. Sprout is a Windows 8 desktop. But it’s also a dual-screen creative console with its own projector, a giant touch-enabled screen and a 3D-capable scanner. The product is the result of a partnership between HP, Microsoft, Intel and 3M. It may be innovative and revolutionary, but it’s not cheap — it will be available November 9 in the US for $1,899.
