Ever wanted to get your feet wet with Business Intelligence, but didn't want to go through the steps of installing SQL Server, finding some sample data, figuring out how everything works...?

The TechNet team has put together a series of Virtual Labs that you can play with for 90 minutes at a time (and you can do so as often as you would like)

http://www.microsoft.com/technet/traincert/virtuallab/bi.mspx

You get a downloadable manual and a 90-minute block of time for each module. You can sign up for additional 90-minute blocks anytime.
