Getting more out of Vim (Vi Improved)

I use Vim for everything. I started out using it for simple config file edits, bash or Perl scripts,
and trivial notes. I used to use Zend Studio for PHP programming, Quanta Plus, Bluefish, or Screem for HTML, OpenOffice.org for documentation, and tools like gedit for drafting email and longer, personal notes (like my personal "tips and hacks" log file). However, over the past couple of years, I've learned to configure Vim to use it for all of these tasks. To me, it makes more sense to try to use one editor for all of my editing tasks if possible (without writing code, of course).
