Ubuntu Linux in my humble opinion is one of the most user friendly Linux distributions around these days and anybody even remotely interested in switching to Linux should really give it a go. I myself was new to linux and I know first hand how difficult it can get when your first starting out learning something new (especially coming from a strong windows background).
One thing in particular was trying to figure out how to get mp3 playback in Rhythmbox (default ubuntu music player).
Here is the solution:
sudo apt-get install gstreamer0.8-plugins
No problem at all was it.
