Ubuntu is absolutely a beginner friendly OS. If I give a computer to somebody that knows nothing more than how to turn it on, Ubuntu will be no more difficult for that person to surf the internet than it would be in Windows. I’ve been teaching people how to use their computers for more than half my life and the vast majority of problems are ignorant people on Windows. Linux isn’t inherently more difficult to use, it’s just different. For adept Windows users, switching and expecting to be just as familiar is where it gets more tricky.
