Why not just take your configuration with you? I switched machines multiple times and each time it took me just a few minutes to migrate my vim configuration over to the new one.

Especially since I have my vim configuration and other dotfiles in Git. Just git clone and I am done.

Off course that is too much when I am only using a machine temporarily (like servers over ssh), but I can be productive with the default as well. It is just that with my configured vim I am more productive.
