Nice article. It was well written and enjoyed it. I see that this is a reprint. Did you ever publish the 2nd part?

I didn't know about the GROUPING SETS and am excited to see this as an enhancement. Most of these enhancements are things I always felt should of been in the product/language. I've been using 2008 for awhile but I haven't had the need for it yet. I really could of used this in 2005 in a previous job.

I like the pretty light blue decorations around your code snippets. I think though I'd rather have the snippets copy and paste friendly.
