This. Hitting that wall when you're hacking on a file and discover after the fact that your fancy keybind remap isn't on this machine and now it's doing something weird...

Customizations are baggage. I try to minimize them as much as I can, even if it means being a little less efficient on my home system. A side effect is that if a program doesn't have sane defaults I'm not likely to use it, even if it can be made to work better with some tweaking.

I don't go much beyond :syntax on and :set si with Vim.
