If I was willing to use vim (or emacs, nyellin) for my daily editing needs I wouldn't be comparing TextMate to Sublime and listing missing features in the latter :-)
Besides, I knew about the vi trick you referenced, but it often screws up something with the terminal, causing all sorts of issues. Admittedly I didn't try it again since moving to iTerm (I'm suspecting a terminal.app issue), mainly because I have a working solution (TextMate).
It's just that weren't it not for this sudo-feature, I would really prefer sublime (I bought both, by the way, in order to support their respective authors)
(I jest. Vim is an awesome editor and I recommend it to all my friends using Eclipse, Visual Studio, and XCode. But true enlightenment lies in Emacs, where vim is only another mode called evil: http://emacswiki.org/emacs/Evil)
