Microsoft just put on an interesting summit bringing together some very different types of people into the same room for a discussion about user experience and software architecture. Jacob Nielson from the Nielson/Norman Group was there, as was Grant Skinner and thought leaders from Adaptive Path, Ovum, Gartner, Yahoo!, Oracle, Rosenfeld Media, Microsoft, Frog Design, and others. 
Some of their conversations are recorded on Adam Richardson’s blog:
