Two interesting iPad shell-keyboard combos

The following two iPad shells also contain Bluetooth keyboards:
ZAGGmate: Shaped like the lid of a shoebox, it functions as a protective case for the iPad’s screen. It also contains a stand for propping up the iPad. An integrated Bluetooth keyboard is optional. [Source: Philipp Rauschmayer]
Clamcase Keyboard Case: The iPad becomes the screen of the device and, thanks to a special hinge design, can be rotated 360 degrees. Thus the case can either protect the iPad like a closed notebook, be used like a notebook, prop up the iPad at a desired angle, or disappear behind the iPad. [Source: Engadget]
