content: It's happiness until one day you reboot after an apt-get upgrade and there's a blinky cursor in the top left corner of your screen. Then you'd better fucking learn REAL Linux in a hurry or you're not getting your files back. (For clarity, I ran Ubuntu as my main home OS for about five years... this happened to me maybe twice. It was a better OS than Windows XP but not as good as Windows 7. I still maintain that a prerequisite for running Linux is having another internet-connected computer handy to search for answers when your shit stops working.)
