American RIM is not wasting its time: they are trying to defend their position on the market of communication devices with more and more exciting concepts. The latest patent of the manufacturer sketches up the functions of such a QWERTY keyboard device, which has a Trackball under its huge screen, and thanks to the device's gravitational sensor, the displayed picture is automatically rotated. Although there are already similar devices on the market, RIM's patent is different in means that the handheld's operating system would use a real mouse cursor, so its use would be as comfortable as in case of Windows, as the input device wouldn't be used only for changing between menus. It is not yet known when does the manufacturer plans to announce such a device, but we expect them to amaze the public soon.
