Looking at the pre-releases of Gutsy Gibbon, Ubuntu 7.10, I found myself becoming disturbed by the degree to which this popularity has translated into uncritical acceptance.

All the same, I can't help comparing Ubuntu to its Debian parent. Despite its reputation for being difficult, Debian has always had a habit of accommodating all levels of users and helping them learn as they go.
For instance, if you enter dpkg-reconfigure xserver-xorg at the command line in Debian (or in Ubuntu, where it is still buried, if often unused), you have three options for setting your monitor's resolution. In the simple one, you simply select the monitor's size. In the medium option, you choose the resolution and refresh rate you want, while in the advanced one, you can enter the monitor's specs directly from its documentation. You can use whichever one you are most comfortable with, but, at the same time, you are aware of other options, some of which may be more precise than the one you choose. Such an arrangement avoids overwhelming new users while letting them know that there is more to learn at some later point.
