I learnt C programming and a lot of stuff about UN*X systems from my Amiga 500 and later on a heavily expanded 1200, thanks to a wonderful "Geek Gadgets Version 2" project. I even ran GCC on my Amiga back then. After that, in 2001, I switched entirely to GNU/Linux (RH7) and I knew quite a lot about how to use it since day one, thanks to my wondeful Amiga computer and Geek Gadgets.
