Also, Gentoo is a great school. If you want to learn how a Linux system works, and really want to learn about Unix systems, then Gentoo is the best for you. The huge knowledge base is one of the things that make Gentoo as good as it is, and left the users without excuses when they break the system. With the power of the CPUs growing every day, the -long time compiling- idea is becoming irrelevant, this way, I see more benefits on continue using mi beloved Gentoo and feel users have less excuses to continue using other distros, but, they are free of choosing, I choose Gentoo because Gentoo lets me choose...
