Yeah, and its a good thing that video is now an option.
When I was a kid, often in the position of helping old people with computers, there was a major behavior difference I often observed.
I looked at the screen "globally", and would identify elements of interest within it. So you could tell me to find something on the screen, and I'd look at the whole screen to spot it.
They had a small mental "viewport" (maybe 2"x2") whilst looking up through their bifocals, that they would only be able to notice elements within. So you first had to steer their viewport to the right region of the screen, and only then could tell them what to look for within it. This gets especially frustrating when dealing with a windowed UI that could ostensibly pop up a dialog box anywhere.
