I'll just go ahead and shill acme: If you want to learn the Unix programming environment, vi and emacs are good in that they will work mostly as expected on any OS, but that's because they don't assume that you will use any user level applications. On acme, it's assumed you that have a shell, plumber and a whole load of commands and scripts ready to help out (as well as a mouse). In the process of learning Unix you learn acme for free and vice versa.
