When I first went to college in 1993 I was fairly inexperienced on computers. I'd had a Commodore 128 and spent hours upon hours keying in programs from Ahoy magazine, but later in high school never really worked on a PC or a Mac. So when I got to college and was thrust into needing to use the computer labs, I quickly got frustrated by having to wait in line to use a computer.
I quickly noticed that these engineering workstations in the corners were almost never used - these were the SunOS days and most of them were Sparc 5's, 10's and the rarer 20's. I quickly started using those and fell in love with Unix and how it worked. The commandline seemed really natural. After that when I needed to use a Mac or PC it just seemed to suck.
So, fast forward to late 1994 or early 95. My first Pentium 75MHz PC I put together needed Linux, so I downloaded Slackware to floppy and off I went.
