Change in time
These are two monitors I use for my computer at my apartment. Both are Dell Ultrasharps but the difference is one was made of ten years ago while the other is about a year old.
Helmer mentions in step two to think about when the item was created which leads directly into step three where the viewer should take into account the shape and form of the item itself. As one can see these two monitors look very different from on another. The older monitor on the right has rounder edges and features compared to new one on the left. In addition the placement and functionality of the buttons on each is significantly different. Really, its just interesting to look at how the style of everyday items has changed over the past few years and how each of the monitors has captured the change.
