4. Logitech Solar Folio case

For night time typists, Logitech has packed solar cells into its latest new iPad case to give the built-in Bluetooth keyboard a battery life of up to two years after a full charge. Soaking in light whether indoors or outdoors, it also has an instant On/Off function to wake up your iPad when you unearth it from its sleepy slumber, and can be used as a multi-view stand to enjoy the Retina Display from multiple angles.
