This is one of the things people usually want to change right away. By default, Emacs saves backup files in the current directory. These are the files ending in ~ that are cluttering up your directory lists. The following code stashes them all in ~/.emacs.d/backups, where I can find them with C-x C-f (find-file) if I really need to.

On mac keyboards, the command key placement works better for me as Meta rather than the default (Super), because it's right where my muscle memory expects a PC keyboard's Alt key.
The control keys are typically pretty terrible, too, but I find it easier to rebind Caps Lock to Control in the system preferences (which is a nice thing to do in other environments, as well).
