On the Emacs development list there is long thread (you can find it here) about the "Emacs learning curve" (this is the name of the thread). The participants have various opinions about why some people may not want to use Emacs. If you gave an Emacs a try in the past and then chose an other editor/IDE instead then please describe in your answer here the reasons which made you look for an other tool.
Your answers can give some real world input to the developers on how Emacs should be changed, so that new users can discover its powers and don't give up trying. Thanks.
