1. You might not have a tiling window manager in the first place (there are no decent ones on OS X that don't require manual operation to my memory).

2. You work on a remote machine and prefer to have your window layout remembered there, so it can instantly be restored no matter what computer you're physically working on, whether or not it happens to have or even support your favorite tiling window manager.

3. It's simply easier for me to do everything within one terminal window full-screened on a 27 inch monitor. It's less context switching.

I completely agree with 1 and 2 - my question was related to a local machine with a tiling WM.

For 3, can you elaborate? How is it less context switching? You're doing the same set of operations in both settings - switching, moving and resizing terminal windows (whether real or virtual).
