What I Learned From Assignment #3

I learned that people get a wide variety of money out of their ATMs.  It was interesting to see how people responded to their questions.  A lot of people had very different answers but most seemed to understand what the conceptual model of the ATM was.  It would be interesting to see how much that would change if you asked people outside of the Computer Science area.  For instance I asked the questions of my wife and my mom these people have a decent understanding both from their own usage as well as being around someone as analytical as I am.  I wonder if that would change if you asked people who are not used to breaking down how and why things work.
