Just a heads up from DevFish (http://devfish.net), a free book on writing applications for Windows 8using html, css and javascript by Kraig Brockschmidt .
You can find the book here:

I have not finished reading this but so far it looks like it will be a great resource if you have any interest in trying the windows 8 javascript programming model.
Besides all the aspects of controls, library support and animations the book also talks about how to make your own components in c#, vb or c++.
Great keynote and I don’t like keynotes..
Seeing the great breadth of large and small devices and the number of manufacturers along with the software vision for Windows 8 and Windows Phone 8 was inspiring.
Jordan Rudess demonstrates Tachyon on Windows 8
Then he played for a while too..
I especially liked Steve Balmers 82” slate!! Can I have one!

And best of all, they finally released the Windows Phone 8 SDK.
