Is Amazon likely to fight the iPad incursion into eBook territory by doubling the amount of screens? According to this report, they have just been granted their patent on an eReader which sounds like a large-scale version of the Nintendo DS - here's info from the patent application:
A handheld electronic book reader device is equipped with dual displays. The device includes a first display for presenting visible representations of textual or graphic content related to the electronic book. The device also includes a second display positioned alongside the first display. The second display includes a plurality of graphic elements that correspond to portions of the first display.
...Also, the second display is responsive to user input to one of the graphic elements to perform an action on the content that is shown in the portion of the first display that corresponds to the one element.
It might be telling though that the application was first filed in 2006...and given the speed at which the eReader sector is evolving, this design may well be obsolete already.
