Silver, there's no operating system you could master out of the box. With Ubuntu and other Linux distros you can't even ask your mom/dad/brother/friend/teacher (in most cases, that is). For the last seventeen or so years Windows has been dominating both household and work usage and it hasn't changed much after Win95 - on the outside, that is. When things don't work the Windows way that's hard coded into your spine, you're bound to study a little. And a little more...
I earn my living by helping people with Windows based computers, so I should know the basics. So far I have quite easily managed to find out how to uninstall programs, connect to the net etc. by just examining the menus and adapting my former knowledge, but the first contact with Windows8 was even more problematic than my few Ubuntu adventures. I've also had a couple of Mac experiences which caused some head scratching before I could do some basic tasks.
So, I'm no Linux missionary, but I can see its benefits. One thing is security until it comes more popular than Windows. Another thing is adjustability. There's already Ubuntu versions readily tailored for making music and other audio material, preinstalled with appropriate programs and all for free. I bet that version would be far from the best business version of Linux, though.

As the titles show, you don't have to try to tweak one distro to fit all your needs. Someone has already done it for you. Fine tuning is another thing, but that's something you'd have to do with every operating system including Windows.
