This keyboard is awesome. Bluetooth communication is rock solid. Battery life is very long and lipoly based.

My only gripe is that as far as I know there is no Setpoint software compatibility for Windows 2000. So I am not able to run the advanced Vista functions. However the basics work just fine as plug and play. Sound controller, mute button, and mouse work great. The only issue I found was that during bootup, while it works to make BIOS inputs I could not later select which disk to boot (xxClone) prior to Windows starting. This was fixed by setting an option in the BIOS to have keyboard control through BIOS. Other than that it has been plug and play.

When I am finally forced to get Vista I get all the other features. The only thing Logitech should change is to add a activation light for the Caps Lock.
