It's little bugs like that in the installers that probably turn off the most newbies. If they're given a working system where they can connect, print, and listen to music, they'll explore the rest themselves. But if they can't hear anything from their speakers and have no idea what to do about it, it won't be long before they say "screw this." Granted, I've never had a flawless Windows installation either, but a really dumb chimp could figure out how to install print drivers in Windows so it's never such a big issue.
One thing that the author never did was check online documentation and forum searching. A Google would probably solve a lot of his problems. If he's willing to use the help that comes with the distributions and search man pages, he should also be willing to search for information outside of the manuals. A little more reading could have prevented a lot of errors and misconceptions he had.
