My daughter comes to me, laptop in hand, gives it to me and says, "Daddy, I'm tired of Windows! It keeps getting slow and I think I got a virus again. I want you to put Ubuntu on it." I was more than happy to oblige her.
What made it easier to make the transition was that her favorite music player was Clementine and it was available in the Ubuntu Software Center too. I also added several other programs that I knew would be useful to her needs...Chrome, Arista transcoder, Tag Tool, Skype 4.0, Gimp 2.8, and a few others. When I came back home from work, I asked her what she thought of it. She gives me a big hug and said that she couldn't put it down all day. She loves it!!!
She likes the Dash, The Launcher and most of all the Quicklists. Ubuntu FTW!!!
