I don't know, I run dwm on my 11" wide(ish) screen laptop, and it works for me, certainly better than a more traditional WM: generally, the less screen estate you have, the more it pays to make efficient use of it. If I'm coding in Clojure, I have a vim window on the left, and a repl and a plain terminal (mostly for leiningen and git commands) stacked on the right. I could set this up in a traditional WM: but [a] it would take (a bit) more initial effort and [b] more importantly, with dwm I can temporarily bring in extra windows (e.g. a web browser) and then get rid of them again without having to restore my layout from scratch. I agree with you about focus follow mouse (though it can be more trouble than it's worth if you have an overly sensitive trackpad).
