I have to bounce between documents, emails, and text editing all day. Everybody processes information in their own way, but for me the learning curve for a tiling WM was only a few minutes and it made doing my work much easier. I can be looking at 3 or 4 things for a project without tapping a bunch of times and going back and forth. Same goes for bookkeeping and all of the other things that I do that seem to require looking at 4 or 5 things at once.

When I'm outside of my preferred tiling environment (especially on Windows or a Mac), I feel like the window manager is me. I can get by using shortcuts, but I feel like I'm just attempting to approximate a tiling experience while also dealing with a higher cognitive workload moving windows around, zooming out to find something that is open somewhere in the background, remembering whether the file I was looking at was a pdf/jpeg/word document, etc. My tiling workflow really helps me ignore that kind of stuff.
