1. I never used IBM
2. My first Os was Windows 95 & windows 98. Both on dual Boot.
I was using computers in school in 98,99 I guess But I got my first computer in year 2000. I didn't even now which model or what was that. I just knew It was Computer @ that time. I was 11 years old and I used to enjoy it playing, customizing look, and learning basic,logo,.
