G'day
@rAIner-linux from DownUnder (Australia) and welcome to linux.org
Fortunately the makers and operators of the world's top 500 supercomputers don't agree, and run Linux, as do most of the Web Servers of most of the largest websites in the world, but perhaps you already know that.
When I was your age, I made the decision to stop using Windows (7) in favour of Linux, which I had been using intermittently for 4 years prior, and I have never looked back.
Although I have had computers such as HP, Compaq, Asus and other, I keep coming back to Dell, because it is so Linux-friendly and reliable.
In any event, we look forward to engaging with you in your journey.
Cheers
Chris Turner
