There is something liberating about using an operation system that not only is free, but completely open source. You have the option to take this operation system and modify it in any way you want, for free, as long as you too publish the source code to any changes you made to the Linux kernel. This is one of the most powerful assets for Linux, and is the driving force behind adoption.
When it comes to computers now-a-days the reality is not many people are choosing to buy a desktop. And why wouldn’t you? You can get an almost limitless variety of laptops which cater to all needs, thus rendering a desktop obsolete for almost all but the most demanding of users.
So with the majority of users using laptops, this begs the question: what are they running on these laptops?
The reality is this, those who choose to buy a Mac almost always run Mac OS (obviously) with the occasionally user choosing to also run windows along side it.
