Logitech Wireless Solar Keyboard K750

Our top pick, this 1.6-pound wireless keyboard gets a charge from sunlight or indoor lighting, so it never needs batteries. You can download software to monitor the charge level and measure available room lighting. You can also program keys for quick access to e-mail and your desktop’s search window and calculator. We typed faster and more accurately on the keyboard, which has springy Chiclet keys, than on the other models we tested. Even indoors, the keyboard worked all week without a glitch. Cost: $80
