Tiling can work if you have a large enough screen. Consider, however, folks that use a larger font size to reduce eye strain and work on a smaller laptop screen for portability. Also, there's a lot to be said for arranging your work area for focus and productivity -- eliminate unproductive pixels.

If I was 22 years old and had a large wraparound gaming monitor, then a tiling approach would probably work well. Truly, that approach did work for me when I was in my 20s. I'm still pretty interested in the VR office idea, but haven't bit bullet on it yet.
