Yeah, but that's a good way to sell vim. Once you've shown someone vim and whet their appetite, it's probably best to show them about 2 or 3 features and let them fill in the blanks while being at least minimally productive.

I've recently taken this approach to emacs and org-mode. I'm a long-time vim user with a super-optimized vimrc, so I know what productivity feels like. I threw in spacemacs to reduce the learning curve, but I still was initially much less productive with org-mode and emacs than with markdown and vim for my TODO lists.

Now, after using org and emacs for three weeks, I'm at the point where several of the amazing features that I had heard about are in my bag of tricks, and it feels awesome! But I've barely tweaked my .spacemacs file, have only learned a bit of org, and am sure that I am nowhere near peak comfort/productivity/flow. But if I had tried to learn all of the things that I know are cool about org-mode, emacs, and spacemacs all at once, I wouldn't have gotten any work done over the past few weeks, and honestly I probably would have given up.

TL;DR: the fancy stuff is the best marketing, but it's best to start slow.
