Gmail was pretty revolutionary when it came out, and nearly everyone in that 14-25 age group uses Chrome.
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.
>Young people, 14-25 are going to buy these and make them cool.
No, they are not. These are going to come to nothing, maybe some more fluff pieces. If I'm wrong, be sure to leave a comment here in the future.
Young people, 14-25 are going to buy these and make them cool. Not the 35 year old engineers who bought Google Glass.
Google has never made something cool. Snapchat was cool out of the gate.
