Rigid form factors

A bar (or slab, or most commonly in the U.S., candybar) phone is in the shape of a cuboid.^[1][2] It is named because of its resemblance to a candy bar in size and shape. This form factor is widely used by a variety of manufacturers, such as Nokia and Sony Ericsson. Bar-type mobile phones normally have the screen and keypad all on one face. Many touchscreen phones such as the iPhone are candybar phones, but do away with keypads, favoring a touchscreen that covers the entire face of the phone. The Samsung SPH-M620 is a unique take on the bar form factor, offering different devices on either side of the bar; a phone on one side, and a digital audio player on the other.
