Logitech's Solar Keyboard Folio adds a clever twist to the crowded iPad keyboard case market by introducing a solar charger. Better yet, standard room lights charge the case; sunlight isn't required.
The flexible folio-style case orients to two different angles: one for typing, and one for media viewing at an angle, which covers up all keys except for a row of media-oriented controls on the bottom. The case also has the automatic wake/sleep feature.
I personally like this case a little better than Logitech's Ultrathin Keyboard Cover because it protects your whole iPad, front and back. That said, it is a little floppy and I wish the inner portion of the case -- the part that holds your iPad -- was detachable. That missing feature would make it much easier to hold your iPad in one hand when you didn't need the keyboard.
Even with those small gripes this is one of the top keyboard covers out there (it also works with the iPad 2). Logitech claims that, on a full charge, the Solar Keyboard Folio's Bluetooth keyboard will last an astonishing two years when typing 2 hours a day.
The Solar Keyboard Folio is currently available for preorder and costs $129.99.
