I came to the same realization when I decided that my wife's live was simpler if she stick using windows In those times the X server tended to die from time to time and that was a worry I didn't want to put on her.
However I think canonical has been doing a good labour in making linux a household desktop name, but what did they got from it, the whole community bullies them as sells outs. Frankly, I guess geeks don't want linux to succeed in the desktop so it can keep being something of the “elite,” despite geeks evangelizing their friends about using linux, the don't want it too be too popular. Just like when you found an underground band, and you got to love it, and you presented it to your friends, but the day it appeared on Mtv you felt they sold out.
