Many people take longer than 2 hours to learn how to do simple things on a computer. Especially in the past, when UI wasn't as good, many people had serious trouble using computers.
I think we can both agree that computers were a worthwhile technology that was worth spending time learning to use.
The fact that playing with these models for 2 hours a week after they came out isn't enough, does not mean that other people, given time, can't use them for crazy things and/or build crazy things around them.
