You're right. It's not that difficult of a concept and luckily Linux works just like that. I will admit that Linux wasn't always user friendly but it's made leaps and bounds in that department. A bit less than a year ago, I decided one day to wipe my SSD completely and install Linux and I've been using it ever since. I'm doing everything I was doing for. Obviously this is going to depend on your specific needs but for me it's been just fine.
