Seems this very well done interface by Pentagram for Wells Fargo’s ATMs was done in WPF:

Expression Interactive Designer and its Visual Studio counterpart increase collaboration between design and development so the process is not only faster, but also less expensive.

I’d love to sit down with those developers and get their honest opinion on the WPF/XAML workflow. I know what you say for case studies, and I’m betting Microsoft threw some cash at Wells Fargo to subsidize the project (I hear they do that), but maybe I walked away from WPF with a completely different take on the technology than others.
