Here's a first: a mouse and keyboard combo with "up to" three years of battery life. Dang. The Logitech Wireless Desktop MK710 uses the 2.4GHz band (thank goodness, no Bluetooth), transmitting your input via that ultra-small Logitech unifying receiver.
The keyboard has a cushy palm rest and concave "Incurve" keys, and the laser mouse has that wonderful hyperfast scrolling that we adore in the Logitech MX 1000 and other Logitech mice. If that claimed "up to" three-year battery life is for real, this could be the desktop set to get by the time it arrives for sale in April, even at its relatively steep $100 price.
