Logitech cordless

There may not be tiny LCD screens on each key, but Logitech's new high-end Vista-friendly keyboard-and-mouse pairing, the $170 MX5500 Revolution Cordless Desktop, does have an integrated display for time, calculator functions, media controls and incoming messages.
The price includes the MX Revolution laser mouse, typically a $100 value. It also includes Bluetooth 2.0 integrated throughout the system.
