I've been an enthusiast of GNU/Linux/BSD since I first tried SUSE 4.2 in 1996, after miserably failing to install a Red Hat distro. Those were tough times for installing a double boot system with Linux, I can tell you. Many times I would install a new distro only to see a terminal screen that I could make no use of. Happily Linux has come a long way since then in terms of friendliness, ease of use and performance. I might be considered a senior if time means anything at all for that matter. I use mainly Ubuntu and often take a look at many other distros, particularly when there are major changes or special features. I believe in the cause of GNU as defined by RMS.
