i never used MSDOS and i actually only started learning how to use a computer beyond AOL when Windows XP came out. i was the one in my family that had to know how to fix all the problems 😛 now i'm the one in the family who knows the most about Macs and was responsible for my parents' switching although i owe my own switching experience to a friend.
when i did the poll, i had 12.5, 37.5, 25, 25, and 12.5 which is 112.5!
