Amazon offers the Logitech K750 Wireless Solar Keyboard, model no. 920-002912, for $39.99 with free shipping. (MacMall charges the same.) That's the lowest total price we could find now by $8, although it was $10 less last March. This wireless keyboard is powered by light and measures only 1/3" thick. Note that this is not the Mac-compatible version.
