I wouldn't say it's as easy as setting up Windows, but it's not anything difficult, if you're even slightly computer literate.
To someone that buys a computer and doesn't bother to learn anything about it, just uses IE and OE to surf, get email, and maybe installs AIM, they'd probably be lost right at the beginning where it asks if you want to set up a Desktop, Workstation, Server, or Custom install.
I went with Custom to make sure I would have access to choose the packages I wanted installed. Wanted to make sure FireFox/Thunderbird/Gaim got installed. Gaim was automatically selected, but FireFox and Thunderbird I had to put a check next to.
