I remapped the Apple key for alt on my MBP. It truly is frustrating; alt is not in a very nice position at all. FN is where I would prefer ctrl to be.

When I really need to get writing at home, I plug in a MS N4K and go at it.

See the sibling comment by raju for the specifics, but you can actually bind the Fn key with the `mac-function-modifier' variable.

I'd thought for a long time that Fn was a hardware/OS-only key based on the lack of apps that use it, but it seems Emacs has found a way.
