One of the materials of the US Patent Office contains the info on a Nokia’s product. It seems to be closely related to the upcoming touch interface S60 Touch. This is a clamshell phone with two displays and one of them can be used as a touchscreen to control the device or a secondary display. The switch between two modes runs automatically depends on the opening angle. 160 degrees reveal the touch panel and 180 degrees (the full opening) make the secondary display. Naturally Nokia isn’t the pioneer with the idea of the touch display instead of the keyboard. However this very solution on the new S60 Touch interface might be very interesting.
