Why is everyone so upset about this? It is a dynamic part of the keyboard. I would be shocked if there was no option to set it "classic mode" for certain applications (or even universally if you wanted), which would have the ESC key and the function keys. Why the opposition? Having a dynamic part of a keyboard is pretty innovative, what are some of the possibilities, I am not 100% sure but I am sure that developers will find neat and useful (and probably unexpected by us and by apple) things to use it for.
