It is possible to adapt fairly easily between different setups. I've got a fairly advanced zsh setup but do a lot of admin on a mix of Linux, Solaris and BSD where I have to put up with whatever the defaults are. I resisted vim for a long time for similar reasons: when doing admin, I often only had vi. When I finally took the plunge and learnt how to make effective use of vim-specific features I regretted not having done it long before. And I can still manage fine on a bare install of Solaris with vi.
