I wish I had more to post about the "other" alternative to Microsoft: FreeBSD Unix. Fortunately TechRepublic's
Jack Wallen Vincent Danen has just written a
"FreeBSD 8.0 installation walk-through" to guide you through installing the latest version.
Unfortunately, FreeBSD is a great operating system with an unholy awful installer — compared to other operating system installers currently available. Some people are comfortable with text-mode installers, some aren’t.
I guess I'm in the "comfortable" camp. Debian uses a text-mode installer, and I always use the text-mode installer when I'm putting Ubuntu on a computer. Really, text-mode installs are no different from graphical installs: the questions are the same, you just use the keyboard instead of a mouse to make your selections.
Update: I misread the by-line on the Tech Republic piece. My apologies to Vincent Danen, the actual author.
