I have recently written an introductory article on Snapshot Isolation in SQL Server 2005 for the PASS Special Interest Group.
The article titled Another Version of the Truth can be found at http://sigs.sqlpass.org/tabid/35/ctl/ArticleView/mid/349/articleId/294/Default.aspx.
This article will also be featured in the August 23rd PASS Connector, so keep an eye on your Inbox.
