A lot of people used to carry pens on their shirts

Isn't "pens in the front pocket" a defining characteristic of a 1950s-era nerd?

If it works well enough, of course it will be cool. Once everyone has one to get shit done with, "cool" will be one of the biggest differentiators to determine which one to get.
