Oh, I see.
In my mind the most important thing that Ubuntu has done is to break with the traditional mindset of linux distributions and just say this out loud: the user doesn't have to know anything. Other distros set the bar at different heights, but they all draw the line at a point where "those who aren't clever enough to follow this don't deserve our support".
What Windows did though, was to really include everyone, and everyone does actually use it now. I think Ubuntu understood that and they certainly have taken to it. They're not the first to do it, but they were the first among the big distros.
I also think the mindset is changing, somewhat. But not all that much yet. Fedora doesn't seem to have changed their approach, perhaps Suse is doing it.
