My husband and I were discussing(agruing) about when people started using personal computers. So when did they become affordable that the everyday Joe Blow could afford them. I'm saying that around the first of the 1990's and my husband thinks that they were out in the 70's...NO WAY! Help solve our arguement...HAHA! I'm thinking that until Windows based operating systems came out noone really knew much what to do with a computer without formal training.
