> After a few years, your VIM will become extremely customized. You'll actually have trouble writing code on any other IDE.

This would actually be a significant detriment to many Vim and vi users who do system administration, because they can't rely on any customization when the drop into a terminal on a random server.

The one thing I really wish the browsers would adopt is a reliable vi/emacs toggle for text entry windows. Vimium, vimperator, etc, they're never reliably available, always at the mercy of the upstream browser.
