I've been asked few times for the slide decks of presentations I have done recently on overview of Windows Azure and on what's new in .NET 4.0.  You can find them here:

Cloud Computing: Practical Innovation (November 2009)

What's New in .NET 4.0 (September 2009)

Please note, there are notes in the Notes section of each slide that help to understand the content when needed. Hope these help someone.
