I often hear that one should not customize their Vim settings because when they have to use another machine they will be at a disadvantage but I must say that I really cannot understand this attitude.

My .vimrc is has a good deal of custom stuff that I rely on during day to day coding, but on occasion when I have to use, say, busybox's 'vi' (which by the way isn't even quite POSIX) I very rarely have any trouble at all. Certainly not enough trouble to negate the productivity gain I see with my .vimrc.
