Also, it doesn't even make you that much more productive. I love it to bits and use it exclusively, but it's just a bit faster, it's not going to reduce the time it takes you to actually think about the things you have to write.
I agree. The most utility I get out of VIM is quick formatting. I'm very particular on how my code looks, (I want to make things as painless as possible for the next guy), and navigating code in normal mode is much faster than anything I could do with a mouse. As far as writing code goes, typing 120wpm makes me fast, not VIM. As far as thinking goes, Jarnal and a Wacom tablet help me do that, not VIM.
