Twenty years ago, when I first started using Linux, finding a distribution that worked, out of the box, was an impossible feat. Not only did the installation take some serious mental acuity, configuring the software and getting connected to the Internet was often a challenge users were reluctant to attempt. Today, things are quite different. Linux now offers distributions that anyone can use, right out of the box. But, even among those dist...
