I was less-than-thrilled. We're a new Actuate 6 customer, and the training documentation consisted of printouts of their PowerPoint training presentation. To make things worse, they hadn't even updated the version number to be "5" on the slideshow. The content itself worked fine under 6, and you can read between the lines there to determine the detail level of information in the training session.
The session itself was extremely useful, but it was pretty hands-on, and they didn't have step-by-step howtos or anything.
