(from the author) Can totally understand how for some folks this isn't an issue at all. But for spastic me it was a stubborn one I found myself losing time on. Perhaps in part because I have my repeat rate jacked way up using KeyRemap4Macbook - http://pqrs.org/macosx/keyremap4macbook/.

I'd Cmd-Tab my way into Finderland a few times a day and inadvertently trigger new Finder windows instead of new Chrome windows with Cmd+N - stuff like that.

Getting Finder out of the rotation prevents this from happening. While I still might double-tab back to the original window, I usually spot that before too much typing b/c it's where my eyes originally were looking.

And aesthetically I'll always take the less number of icons when I can.
