I wanted to switch to i3, a tiling window manager. There are some things that are better, and some things that I miss. I run Ubuntu 16.04 LTS and Unity provides a lot of functionality that makes using the computer effortless. The motivation for using i3 is that, while developing, I end up tiling all my windows in separate workspaces anyways. It seems like the natural functionality of i3 better fits my use-case.
