You just have to learn it, period. It seems daunting but it's not as hard as some people make you believe it is. I admit vim's plugin system is bad and vim doesn't have a nice API subl has for extensions, but there are experts who write great vim plugins so you don't have to and worse comes to worse, you don't have to load up your vim with plugins to be productive. I have another co-worker who uses vim and is very productive and does not use any plugin at all.
Finally, if you're a new developer, don't listen to the op. Spend a few weeks to learn vim, or emacs for that matter, and you'll be so much better off in the long run.
