Isn't the apple market getting soft? The app gold rush is over and it never was a very good deal to begin with. Apple wants a cut of your development profits, they can yank your app or worse, yank your developer account arbitrarily. Swift, while not finished yet, commodifies the the apple dev market further. I don't think devs have a choice, they have to move on to other markets.

The esc and F key is a red herring. I do most of my coding on a Das Keyboard.
