The AutoCAD User Guide located in the online Help and also in print has continually improved release after release. I ran through some of the content the other day to polish up before presentations I have scheduled. I was very impressed at the clear concepts and illustrations on AutoCAD topics in the new release. I found myself reading it like a book for fun which I had not done in a very long time. I would encourage you to have a look when you get AutoCAD 2008 and also have a look at some of the animated concepts called "Show Me". I was especially impressed by the section on rendering and annotation. Also if you find areas to improve or want to send feedback on specific Help content select the option located at the bottom of each online help page "Please send us your comment about this page".
Below is a screen recording for the "Show Me: Scale Annotations Automatically"
