Fresh off the announcement of their solar-charging bluetooth keyboard case for the iPad, Logitech is back with a new solar-charging keyboard, the Wireless Solar Keyboard K760. However, there's one powerful feature in this keyboard that will make it extremely attractive to power users: it has the ability to pair and switch between multiple devices. This means that it could easily be connected to the Mac, then taken to another room with the iPad, and then on the go with the iPhone, with its ability to switch between three devices. The multiple device support, combined with the fact that it doesn't need to have its batteries replaced, and its similar layout to the official Apple Bluetooth keyboard, may make it a more attractive option for anyone shopping for an Apple-compatible keyboard. Now, if only they could find a way to make the Magic Trackpad solar-powered. That thing eats through AA batteries like Pac-Man. The Wireless Solar Keyboard K760 will be available this June for an MSRP of $79.99.
