I think this mostly shows the significance of proper domain scoping. The handheld device may have all listed features, but it has a very narrow user profile.

As lecture 4 is already too full, and this is a good example of a "Wollmilchsau", maybe this belongs in the introduction. For example, on slide 15 (What is a Domain?), scope is mentioned (we could move the three images to a box 'example domains' and the product map to a 'scoping' box). Or on slide 6, we could replace the swiss-army knife.
