Otterbox ( has released its Defender and Commuter series of iPad cases. The former (US$89.99) combines a two-piece polycarbonate shell lined with soft felt, silicone outer skin and a self-adhering screen protector for protection.

An additional polycarbonate cover snaps over the face to protect the Multi-Touch display or can function as a built-in stand while browsing the web or watching a video. Silicone grip pads on the bottom of the case prevent the iPad from sliding when sitting on a flat surface. The case also accommodates the optional dock accessory.

The Commuter Series case ($64.99) sports a self-adhering screen protector; the device is then wrapped in durable silicone and fortified with a one-piece, custom molded polycarbonate shell that snaps over the outside. Layers safeguard the iPad from unsightly scratches and dings and make it easy to slide out of any backpack or briefcase. The case also features snap-off access to the optional iPad dock.
