Me too, although I started with Mandrake 7.2 around 2000/1. But then I decided I was a big boy and after 8 years I switch to Arch now. I did experience other distros like Ubuntu, Debian, Fedora, SuSe and minor ones like Puppy Linux and Linux From Scratch. But mostly out of curiosity and testing.
But Linux had been my primary desktop since 2002/3 until now
