I use emacs but I also dislike the "you can rebind any keys you want, as long as the sequence begins with C-c". As it turns out emacs doesn't user the super key at all (Apple key on Mac keyboards, Windows key [I think?] on Other). You can dramatically increase the number of comfortable chords available to you by taking advantage of this, e.g.: (global-set-key (kbd "s-l") 'forward-word)

While the OS-specific keys are sometimes called super, they are not "super" in emacs terminology. Also, if you skim M-x describe-bindings you will find quite a few bindings beginning with s-.

EDIT: If you really want access to a less crowded namespace, using (global-set-key "\C-z" nil) to free up the c-z prefix and binding Hyper are popular.

If you are feeling a little confined, key chord[1] will allow you to get creative with your bindings.

Not using a Super key is actually a great feature. My Super key is used solely in the AwesomeWM (a window manager) commands, so the two (awesome and emacs) never clash on who will handle a key combination.

I was very unpleasantly surprised when I discovered that OS X uses a single Control key for some of its hotkeys (like C-up/down) which I bind in Emacs for my own purposes.

I've never paid attention to the C-c convention and liberally bound commands to whatever key I preferred.
