Good UI Designers Rock!
I've been playing around with xaml technologies for several years now and it's given me the utmost respect for truly good UI designers.
In the era up to and including Win Forms I'd always thought of myself as a competent UI designer but xaml has change all that. Quite simply there are so many options available in xaml UI design that I've realized I just don't have the aesthetic sensibility to create top tier UI any longer. My hat goes of to the many many designers that do.
