Since 1985, but mostly just a hobby now. Have not used anything but PC at work in the last 15 years.
"Just a hobby" statement always bothered me, as if making money (making a living) is the most important of all things and hobbies are secondary? I know so many people that would kill to be able to spend most of their waking hours on their hobbies. (I gather that this may not be the case for you and Amiga.)
