I too have both, though have been using a ThinkPad Bluetooth keyboard (with the TrackPoint nipple) more often, thanks to another thread here. Other than having the island-style chiclet keys, almost as good as old-school ThinkPad keyboards.
P.S. Off-topic question, do you guys have any problems running both Logitech SetPoint and Microsoft Mouse & Keyboard Center software at the same time (assuming you use other Logitech and Microsoft mice/keyboards)? How about with a 3rd software thrown into the mix (such as ThinkPad, or Kensington trackball software)?
