That was in 2000. A friend of mine brought me a Slackware clone (I didn't even know what Slackware meant at the time) on four floppies. After some effort we managed to install it.
I noticed that the keyboard layout didn't exactly match my keyboard. "No problem", he said, "just edit that text file and tell the system to use it". I did it, and it got a bit better. Then I tried once again, and again, and finally could not save the file any more.
I had to reinstall from scratch.
It took me several years to switch completely, but Linux had won my heart already.
