Agreed in concept, but you can get similar if not greater productivity gains from stacking/floating WMs that let you move and resize windows into a tiling-like configuration. Examples are goomwwm and subtle.

This "manual tiling" approach is also probably the only viable option for tiling-like window management on OS X. While not nearly as powerful or productivity-promoting as the above-mentioned WMs or conventional tiling ones, the OS X program Spectacle (http://spectacleapp.com) makes life a lot easier on OS X for those of us who are used to the screen real estate and keyboard control afforded by tiling WMs.

Edit: Another commenter mentioned the non-free Optimal Layout (http://most-advantageous.com/optimal-layout) for OS X. I haven't downloaded the trial yet, but the website makes it look very promising.

I've used an xmonad clone for osx [0] for about a year now. It's a lot buggier than xmonad - mostly due to osx's terrible apis - but it gets the job done.

Recent versions of Amethyst https://github.com/ianyh/Amethyst have made a pretty much xmonad-like experience on osx. There are a few quirks but I don't see me going back at this point.
