Comparing Flash and WPF (Silverlight)

There has been a lot of talk lately about WPF/Silverlight. I have also been learning and writing WPF articles, but what I thought might make an interesting article would be to compare and contrast WPF/Flash. I feel I have the right to do this, as I have worked with both technologies, and although I am not selling myself as an expert in either, I feel confident enough to write this article, I thought it would just make some interesting reading for others that just dont know how WPF or Flash work. For example if you're a Flash developer and dont know what WPF is, I am hoping this article will help you, and vise versa.

[We've all had a bit of a set to recently over Silverlight/Moonlight. Here's an article that compares WPF/Silverlight with Flash. - tracyanne]
