I recently bought a Kensington TurboBall with hopes of using it w/ my current workstation, which runs win2k pro. This has been my 3rd purchase of Kensington input devices and they've never let me down with their top-notch control software and tactile use. I'm really surprised at Kensington's lack of commitment to the win2k platform and to its base of loyal customers. As has been stated, a large number of key hardware manufacturers have already showed their support for win2k w/ driver updates and patches. I only hope that there is at least some progress being made at Kensington to deliver these drivers... otherwise, I'm going Logitech from now on.
