I love the new way (I guess that it's since KDE 3.5) of ripping an Audio CD on KDE. You just have to open konqueror, click on "Audio CD" and you have a folder with wav's, ogg's, mp3's and some others... Just drag'n'drop the folder you have to the place you want it... et voilá!

To know more about this usable way of seeing an Audio CD, with screenshots and stuff like that, you might want to click here.
