The DUX 2003 case studies are online - these are the same PDFs that were offered for human consumption on the conference CD.

I'm on a deadline right now so won't link to individual papers, but favorites include the Constraints panel (but I'm biased, since the authors are all excellent people), the Intel pervasive computing stuff (Connexus & Vineyard papers), the Business Issues panel, the blender redesign from Continuum (again, more excellent people), and a lot of the Informing DUX panel - particularly the MS personas, Bob Baxley's UI model, and a different take on card sorting in the Vacations vs. Groceries paper.
