If you are excited about the release of Expression Studio at MIX '07 then you might be interested in free training videos that cover all the products that make up the suite.

These videos are a great way to get up to speed with the new design products and you can watch them online or download them for watching later. Most of them aren't too long so you can watch them in those times you are waiting for something else to happen (or maybe watch them on the bus, train or flight somewhere).
