Apple's got a new idea to beef up their iPad in the future. The Cupertino company is trying to patent a Smart Cover for the iPad that has an embedded secondary display. Surface just met it's match?
The cover would use a connector on the side of the iPad supplying data and power to the cover. Check out Apple's description of it:
[The] accessory device comprising: a flexible flap having a size and shape in accordance with the host device display, wherein at least a portion of the flexible flap is covered by a flap display configured to present visual information; and a connecting portion, the connecting portion arranged to provide at least a communication channel arranged to convey information between the host device and the accessory device wherein at least some of the information is presented visually on the flap display.
Would you look forward to a secondary display for your tablet? Why not. It looks great. At least, in concept for now.
