Absolutely. Plus, I'm lazy. If I can pick something up for trying stuff out, that's what I'm going to do. I know there are lots of complaints about AdventureWorks... it's too big, it's too small, it's structure is wierd... I think it's a reasonable representation of a database. It's not perfect for all situations, but it works.
