What do I read to gain a better understanding of old-school properly-desktop UI design? By "properly-desktop" I mean multiple windows, primarily oriented at mice and keyboards. With power users in mind, pretty much the opposite of the modern "clean" stuff.
I'm good at copying things and picking up patterns from other people's work, but I'd like to get better at designing my own desktop UIs from scratch.

Is Jacob Nielsen's "Designing Web Usability" still relevant? It's certainly old-school!
