I found this article useful. I also dislike the dock's distraction and limits of monitor space on my Macbook. However, I do need the expose' and command-tab app switching features also.
I use Path Finder (http://www.cocoatech.com/) instead of the Finder which I find burns through my CPU for no reason when no other apps are running. Path Finder is great and quite customizable.
I also use Quicksilver (http://quicksilver.blacktree.com/) and have a few great keyboard shortcuts designated for everything I really need. I have disabled Spotlight and soley use Quicksilver and Path Finder.
Now why can't I just make the dock go away without using the other functions that go along with it?
Theoretically I could use Path Finder's menubar drop down to switch apps instead of command-tab, but it involves mousing.
Any ideas?
