Also the fact that Ubuntu pretty much does everything for you helps as well. I'd say wait until Yellow Dog Linux comes out so everything can be happy and installed automatically. I'm doing that myself.
It's more complicated than just using it. I just installed Ubuntu for the first time over the past week on my PC and just got it working and installed the way I like it. It's less of a "how do you use it" question but more of a "how do I do this certain thing" type thing...at least that's what I did. I searched for every problem I had or thing I had to do on a separate basis.
