I'm 44 too and hate people that maximize their window, as they are so many things running at the same time, don't you tile your applications, ah interesting there is more than one way to do it I guess.
that is valid if you do have multiple things going at a time. I do it frequently.
These students don't have multiple things going. All they have is the browser and I see them having to scroll left and right because the site doesn't fit inside the browser window. The rest of the monitor is just the desktop.
