@McKhenry really, a CD was cool and you could play it with your friends or get the girls, so probably money well spent. A lightbulb that changes colour, I am not sure it is the same, I am far from 19 so would not know. What I do know is my nieces and nephews, all of who are in late teens, early 20s, earning good money, still spend their disposable income on beer and going out, not light bulbs?
