I read so much about why Tiling is Great because the Mouse is Awful.
I think the mouse has its place. For writing code and text I have my hands on the keyboard—which means I also want to create and move windows with the keyboard.
But when I'm in a web browser, or a game, or any number of other GUI-centric applications, my hand is already on the mouse. Which means I want a visual dropdown for launching applications, and I want to drag and resize windows with the mouse.
I love my Tiling because it doesn't waste space. To me, Windowing is just silly; why would I ever want large swathes of my desktop empty, and applications overlapping each other?
But I don't understand the mouse-versus-keyboard argument. I want both to control my WM with both, because I use applications with both.
