A form factor for a portable device is disclosed. A first face of the portable device may house a display screen and three linear input devices (e.g., touch-sensitive strips), one on each of three sides of the display screen, for providing user input. On a second, opposite face of the portable device, is a planar input device (e.g., a touchpad) for providing user input. There may also be a microphone and speaker on the second face of the portable device, with the speaker placed behind the planar input device. Sound output by the speaker passes through holes in the planar input device. In one embodiment, the planar input device is used for scrolling content displayed on the display screen, one of the linear input devices is used for zooming in and out, and the other two linear input devices are used for identifying a location on the display screen. In another embodiment, the planar input device is used to identify a location on the display screen, and two of the linear input devices are used for scrolling.
