I think this is a great post. Microsoft is investing millions of dollars in WPF, and it is true that the .net community is not that excited about it.
Many reasons to that (and I know what I'm talking about). The biggest one is because WPF is something completely new for a windows developper, and it's not easy to learn.
So most of them rather stay on orlder technologies (winform) where they feel more confortable and efficient.
But make no mistake, one day or the other, WPF will prevail, that's for sure !
Here is a WPF application I'm working on :
myBoard(the mac os X dashboard on windows)
