It's rather sad to see that in 2009/2010 that so many users continue to modify their configuration files by hand that there aren't graphical or CLI utilities available (or that they are aware of) that can suit their configuration needs. If Linux is to become a mainstream operating system with consumers, they must not need to be introduced to editing the xorg.conf themselves.
I use krandrtray for simple resolution adjustments, the CLI xrandr utility to adjust multi-display settings, and xorg.conf for advanced driver and hardware options. I generally use Xorg -configure to build a base config file and then tweak a few things from there.
It really doesn't have anything to do with bad front-ends and certainly doesn't degrade the user experience. A new user coming to Linux doesn't need to know anything about xorg.conf.
