Haha nice! I think if you sell computers there will be quite some conversations like this. Smartphones and tablets bring some of the functionality in an easier to understand way to less tech savvy people right now though. Anyway, some concepts like a touchscreen is still hard to comprehend. My mother for example always tried to press hard on the touchscreen of the tablet I gave her. It took some time before she understood thats not needed.
