I think that’s actually the key difference here - OS X apps very rarely make use of the function keys, instead preferring Cmd-letter combos (which to my mind possibly make a bit more sense as you can remember e.g. R means Refresh). That means that doing away with the function keys is probably a much smaller deal for Mac users than Windows users, as on the Mac they were pretty much just used as media keys anyway.
