Thought this article was interesting. In it, we see a list of common mistakes made by new converts to Ubuntu Linux and to a larger degree, Linux distros in general.
Once again, we have another half-baked list. Fear using Google, it might lead you to the long approach to finding Linux software. Seriously? Uh, folks, this is how I offer most of the how to advice to readers wondering why Ubuntu 10.1o blew it with Evolution and MS Exchange is this release and what can be done about. Hint — SSH X forward Evolution from another machine running Fedora.
As for giving up too easily or being afraid of the command line, both are hogwash. If someone isn’t comfortable with the documentation (Ubuntu’s is dated in many places) and there really is next to no reason to use the command line except for advanced usage.
