I just finished checking out a few samples from Apple's new online seminar, Aperture for iPhoto Users. In the samples, Joe Schorr walked me through a few techniques that iPhoto users already know how to do, such as create a slideshow, then demonstrates how to achieve the same task in Aperture.

The production value was good, as you'd expect, and the information was spot on. The seminar is free. If you know an iPhoto user who is thinking about trying Aperture, you might want to point them this way.
