The Natural Ergonomic Keyboard 4000 retains the F-Lock setting that I explicitly set, and Microsoft just sent me an email by way of which I can track my rebate. (The check was mailed on 03/18/2007. Love that time-travel.) I love automated rebate tracking.
I finally have a keyboard that remembers what I told it, has the keys in the right position, and I can watch my rebate roll in.
