However, that's just my experience. I'd suggest he try a clean vim and add plugins as he needs them. There are plenty of links suggesting great plugins for developers. "sjl" (steve losh) has an article which was linked here (Coming Home to Vim) that mentions some good plugins.
I'm sure it has it's problems, but you can easily remove all of the included bundles. I think at the very least it provides a well structured foundation to built upon.
I've been studying other's .vimrc files in an effort to understand what all vim vanilla is capable of. Once I get that dialed in, I'll look into plugins for my local box; I just want to make sure that I can use it effectively just by firing up any new VM.
Also, I'm being sacrilegious and setting myself up for primarily --INSERT-- mode, since its the most like a GUI text editor. Its making the barrier of entry slightly more endurable!
inoremap <Up> <NOP>
inoremap <Down> <NOP>
inoremap <Left> <NOP>
inoremap <Right> <NOP>
noremap <Up> <NOP>
noremap <Down> <NOP>
noremap <Left> <NOP>
noremap <Right> <NOP>
This will get you to stop using the arrow keys for moving around, use either hjkl, or faster combinations such as "f" "t". Hope you get out of insert mode soon!
