Not leaving the keyboard is one big thing. I ditched webkit for Firefox in order to be able to use Pentadactyl, but it's worth it to not have to leave the home row.

Learning a few commands is not hard, and there is always the ol' mouse to fall back upon if you don't want to remember all those commands.

With vimium[1] you get most of the keyboard-functionality in Chrome that Pentadactyl offers for Firefox.

Vimium is awful compared to pentadactyl.
