One of the nice things about Vim in particular is that it's incredibly uniform across platforms - far more consistent than Windows keyboard shortcuts versus Mac shortcuts versus Linux shortcuts. Vim's download page is quite... extensive: http://www.vim.org/download.php Another advantage of learning Vi is that since it's been such a popular choice for decades, there's a reasonable chance of a "vi emulation mode" being available in other environments; the Komodo IDE has one built-in I believe, there are third party solutions for Visual Studio, Outlook and Word, even a system-wide Input Manager plugin for OS X.
