I wonder if it's good for coding: emacs, etc. I have tried a 30" once, and it was so large that I had to move my head a lot, if not constantly, which felt very tiring after a few hours.
What was your setup? I find while two windows of actual code is about my sweet spot, I could definitely use more panes for informational stuff: magit, output from long-running processes, etc. Plus space for the application itself.
