My first experience was in 1998. My grandfather had a computers and even tho he was hesitant to let me use them my mom convinced him saying that I may eventually turn into an engineer like him. I used them mostly for paint and a couple of space shooter games he later got for me. It was great. They always had computers, they even had a c64 at one point and i remember playing with that one as well.
My first computer tho, it was in 2010 while I was in the Army. Still have that lil hp in my office although it does not work anymore.
Nothing speciall really. I've had computers all my life and a mother that was passionate about them. I owe everything I am to my mom. I think that it is because of her that I became a computer scientist.
