Input:
i love this keyboard.  love love love. and the fact that it can be used for Mac (via USB) and PCs makes it that much more of an amazing product.  after years of suffering with wrist & elbow pain as a result of long typing sessions, i have found the solution: this keyboard.  i am SO glad for ergonomics.  it does take awhile to get used to the keyboard setup, particularly if you are a "hunt & peck" typer.  however, this is the 3rd Microsoft Natural Keyboard Elite i have used, and i will never go back.
