I have also used headless Linux machines throughout my Mac vacation :).
With regards to the hard stuff. 1994-2007 was from my 12th to my 25th, basically overlapping with when I was a high school/university student. So, plenty of time and not enough money for a Mac or some commercial UNIX system. That period was also super exciting, especially up till the dotcom crash a lot of people thought that Linux was going to take over the desktop (anyone remember Corel Linux and even WordPerfect on Linux?). Linux did take over, but in different ways than we imagined, the server was kinda expected after the mid-nineties, but Android not.
