Yea, Microsoft!
I had a really happy experience lately with Microsoft.  I've had problems with various early versions of the Natural Keyboard.  Either the arrow keys were not placed for optimal 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.
