User freindliest linux is...
I have tried many and have little patience for distributions that do not work "out of the box" so to speak. If things don't work first time then its a hobby, not a computer opperating system.
I have had the best run out of PCLinuxOS, although it is not the prettiest or the most feature packed.
It has a "Control Centre" that makes messing about with the settings easier than just about any other distribution.
The forums are also very friendly to new users.
