We are huge fans of Logitech. We love their lines of Harmony Remotes and their current line of wireless keyboards and such. Well, they have taken it to another level now, introducing the Logitech Wireless Solar Keyboard K750.
For only $80 you can harness the power of sun (much like Superman) to charge the battery on this one. Never have to worry about replacing the battery again. Which is always a good thing. Less waste is always better.
