New type of keyboard from Logitech

Logitech has now come up with a new type of keyboard that is wireless and no batteries. The keyboard is called Solar Wireless Keyboard K750 and recharged by the sun and is therefore more environmentally friendly than they formerly keyboards. A single charge should last as long as at least three months in total darkness, but even ordinary light bulbs works as a charger for other than the sun.
The keyboard is just 7.5 milimter thick and can be purchased for about 800 kronor in early January
