That's not the same as being cool. Yes, Chrome is extremely popular among that age group, but many popular things aren't cool. For example, the Big Bang Theory is something very popular but even the fans wouldn't say it's cool. In fact many things are cool in part because they are not overly popular, and often decrease in coolness as they become popular. Gmail and Chrome were indeed innovative once, and perhaps you could argue they were cool back then, but today they are just a commodity - people (especially in that age group) just take them for granted, "it's what we use." They aren't cool.
