Difference between paid OS and open source OS

As per my experience and knowledge:

Being Open Source, Ubuntu is FREE and Windows is not.
Ubuntu is secure out of the box and Windows is not even after using some expensive Anti virus software.
With Ubuntu, I don’t need to worry while using my friends pendrive or hard disk but on Windows, I think so many times (means there is very less chances of having viruses in Ubuntu than Windows).
If you choose Ubuntu than you will be going to miss MS OFFICE , but no need to worry about that you can use LIBRE OFFICE instead.
Gamers prefer windows and no doubt why, because most of their games don’t work in Linux yet.
There are so many applications and games which are yet to be made compatible for Ubuntu and their developers don’t want to do so.
Ubuntu is faster than Windows and you won’t need to use ctrl+alt+del anymore.
Ubuntu is more reliable than Windows and you don’t need to waste your valuable time in fixing issues and tweaking thing to make it work faster.
And the best thing in Ubuntu is that no one at home, can mess with your system even if it don’t has password.

Please remember it depends upon person to person according to their working experience with different OS.
