Microsoft is going Open Source

Oh, my godness... Microsoft implements O'Relly OSCON. This must be really fun, how far may it take...
Open Source software labs @ Microsoft, CodePlex (it's only because of Vista Power Saver, indeed), Microsoft Shared Source, Open Source ISV Forum... Sounds really fun, can we have the sources of the next Windows version? See yourself: http://www.microsoft.com/opensource/
