I learned vim and with me is hitting :w<cr> all the damn time. Not to mention pressing <esc> to leave insert mode.

Had to use Android Studio/Eclipse for some time but it was so much harder that I kept trying to find ways to use vim even if I had to memorize or copy/paste package dependencies from Android.

I honestly wish I could use some of the most advanced refactoring tools from IDEs into vim but the way I edit is so ingrained that it's simply not worth it.
