it's lots of little things, the fact that the installer doesn't need to ask you a million
questions spread out over an hours time, but asks you a couple questions up front and then
goes and does it's thing is one of them.
individually they are trivial, but togeather they make it easier for people who don't already
know where to go for everything.
you don't see the difference becouse you are already familiar with the tools and just go to
the right place. but if you were to setup two identical machines with different distros and
give them to people unfamiliar with linux, the _experiance_ (note, experiance, not
speculation) that people have is that Ubuntu generates less frustration and fewer questions
than the other distros.
you don't see it? ok, you don't. nobody is trying to force you to use ubuntu, you are free to
use the distro of your choice.
just do us all a favor and stop bad-mouthing the distro that others choose just becouse it's
not the one you like?
