I thought after Tathams tour of New Zealands User Groups and the upcoming Atlas tour of the regions that it might be a timely time (oops) to point out the blog post that ScottGu posted a couple of weeks ago.
So whether you have no idea what Atlas is or if you want to know more after the tour you should take a look at this post on Scotts blog.
It lists a number of videos/screencasts, books, articles and even a contest.
If you were lucky enough to get a ticket to Tech Ed you'll be able to see Scott present Atlas himself. It should be very good - Scott is consistently rated the best speaker at the US TechEd.
