Since Doug mentioned me doing lots of GUI stuff, I thought I'd mention an interesting UI design book - About Face. It's worth a read, although I think that Cooper goes a little bit far in saying that the "File" menu should be nuked. There are some things that don't always follow a rational model, but get ingrained into the system so deeply that you shouldn't try to change them. I agree with probably 80% of the book though - self describing UI, error messages with intelligible text (and solutions), etc... basically stuff that MS typically does poorly... although hopefully we are starting to show signs of improving.

The question for Doug is - are you going to JavaOne this year?
