Feast your eyes on Sprout, a new all-in-one PC from HP that replaces the keyboard and mouse with a 20-point, 20-inch projected touchpad. HP says the Sprout is the first product in a new 'Blended Reality' lineup that's meant to re-envision the interface between real and virtual, analog and digital. Along with the projector, there's also a high-res camera and 3D scanner, allowing you to easily 'upload' objects into the Sprout just by placing them on the mat.
