Logitech today launched their first Solar powered wireless keyboard. This means no more changing of batteries, and a much slimmer profile. The keyboard can be powered by both direct sunlight or indoor light. On a full charge, it can last up to 3 months of no light (if you intend of typing inside a cave). It also uses Logitech's unifying 2.4 Ghz unifier receiver, which means using only 1 USB port for your new keyboard and a Logitech mouse.
