The authour, Frank Patalong, was innocently using his PC running that other OS yesterday when it locked and demanded payment to continue… He had a router, firewall and anti-virus software. He had often used GNU/Linux as a rescue CD to fix other people’s PCs but yesterday he decided to install GNU/Linux. He did and found it usable. He had helped others install GNU/Linux and instead of requests for help that he expected, he finds users feel GNU/Linux is fast and clean.
That has been my experience for many years. Others are discovering GNU/Linux. It’s all good. I recommend Debian GNU/Linux. It works for you instead of the bad guys.
