One of the most annoying things about typing on a wireless keyboard is the sudden shutdown that often occurs right in the middle of a particularly inspirational key-tapping session. By the time the batteries have been replaced, the muse has vanished. Logitech's latest keyboard is designed to end such woes. The slim, wireless K750 sports a couple of solar strips above the row of function keys which provide the keyboard's power. The company says that it can draw energy from internal lighting as well as the sun and will keep on going even after being kept in the dark for a few months.
