Ubuntu Desktop Course

From the makers of Ubuntu, there now exists an official Ubuntu 7.10 Desktop Course. This really shows the strength of the open source community; the Ubuntu team really goes full-circle with their support. The course is completely free (in both senses of the word), and available for download here. There is a student version, as well as a professor version.

Although it's obviously intended to be taught in a mentoring or classroom environment, this would be a good read for anyone interested in moving to Linux. The read would probably be pretty rudimentary for somebody with a background Linux. However, it would be an excellent overview for somebody not only interested in using Ubuntu, but actually understanding what's going on.
