Accessory manufacturer Logitech is on a roll with its recent successful release of the Ultrathin Keyboard Cover and Solar Keyboard Folio for iPad, and today the company announced the new Wireless Solar Keyboard K760 for Mac and iOS devices.

The US$79.99 keyboard is only available for preorder at this time, but looks like it will be a winner. There's no need to replace or recharge batteries in the K760, ever. A small strip of photovoltaic cells across the top of this keeps the Bluetooth keyboard charged up via sun or lamp light, and even if you're stuck in a totally dark room for the next three months, it will keep on clicking.

One cool feature is the ability to switch between paired devices -- say an iMac, iPhone, and iPad -- with the push of a button. That makes the K760 perfect for situations where you'd like to use one keyboard to "rule them all."
