Been looking around WinFX and specifically XAML recently. Not sure I think writing XML is a great way to write a GUI (but billions of web pages clearly prove me wrong). My first impression is that one of the benefits is going to be automated creation of XAML -- not from tools, but from our own programs.

It's been 10 years since HTML was a household word and I still feel like it's easier to hand write it than use a WYSIWYG tool. I also never really liked using dialog editors. Even good ones like Delphi have too many limitations, especially when it comes to layout. So, I'm not expecting much from the tool support for XAML. But since it's just a text format, it should be pretty easy to generate from a simpler format (or from models). I'm looking forward to playing around with that idea.
