Some good XAML / Avalon overviews

I wanted to find out what XAML is good for so I've been hunting stuff about Avalon and XAML the last days. I found a couple of good ones here:

• The last MSDN Magazine got 2 good articles written by Dino and Charles Petzold - A First Look at Writing and Deploying Apps in the Next Generation of Windows and Create Real Apps Using New Code and Markup Model.
• A bunch of good presentations from the PDC 2003 are available, look for the CLI 3xx presentations. CLI200 and CLI300 are good overviews. I was really impressed with some of the stuff you can easily do with graphics thanks to Avalon.
• Rob Rylyea's Longhorn blog got a few interesting posts about XAML and Avalon.

I'm really impressed by the new graphics capabilities in Avalon, but XAML itself still gives me headache. I do hope for a good designer tool so I don't have to battle with the markup language myself more than adding an event or two. I wasn't sure what XAML was good for first, but separating the code and presentation is never a bad thing to do.

The only thing I don't like at the moment about XAML is the ability to put code in the markup. I wish they could get rid of that and make XAML cleaner.
