Although it's quite long (8 minutes), this demo is a great example of showing the product while focusing on business value...

Goldmine Enterprise Edition

Thankfully, they included a table of contents to get through the whole story. Following a very brief intro, the product is shown while the narrator discusses high-level concepts like tracking and visibility. And rather than wasting time clicking through screen-by-screen, it simply presents them while discussing the product's impact and usage. I would have liked to see a bit more of the large screen devoted to showing the product a little larger, and it would be nice to be able to navigate (via scrub bar) through each of the chapters.
