I got my first PC when I was in class 11 (2011), I was probably 15 years old. It was an assembled PC with 512 MB RAM and 80 GB of HDD running Windows XP with Intel Pentium Core 2 Duo. It was too slow but I was happy that I got one. It opened the world of internet for me and I got to know that you can write lines of code and create stuff. I was so obsessed with this idea which finally led me to Computer Science.
Although this wasn't the first PC I used. We used to have computer labs in schools since we were in class 6 (2006) but that was limited to learning Microsoft Office and Paint (playing Alladin on Saturdays).
It was so much fun back then.
