And to answer the poster, I tend to just use the default vim. I'm bouncing around machines so much that I don't bother setting anything up on my main one that I'll miss on the others...

My cure for that is putting my .vimrc on my site; then, from a foreign machine, I just do:

wget -O ~/.vimrc http://lucasoman.com/vimrc

And just like that, I'm in my comfort zone. Of course, this doesn't cover plugins and such, but I don't use those very often.
