Electronics in your pocket: cool

Electronics in your hand: cool

Electronics hanging out of your ears: cool

Electronics on your head, face, or built into your clothing: irredeemably uncool.

I can't explain why in words, all I can tell you is that the world sees these things differently. If you don't understand why computer-enabled glasses are unavoidably dorky then I can't explain it to you, but I'm pretty sure it's the case.

edit: That's not to say they won't sell well, to certain people. I envisage engineers on building sites walking around with 'em, or travelling salesmen, or police officers, or... I dunno, there's gotta be lots of good use cases for these sorts of things. But the very utility of 'em makes 'em desperately uncool, like Bluetooth earpieces.

I might be getting old, but I remember a time where electronics ANYWHERE in your person were incredibly uncool.

They were called "wereables" from a reason.

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

Now using bluetooth earpieces is commonplace

Sure, among two classes of people: travelling salesmen and complete toolbags.

I am sure people will get used to using very tiny gadgets on their clothing or ears if they assist them in meaningful ways.

Oh sure, I'm just arguing that it'll never be cool.

Yeah... next time you're walking through a crowded place, look at people's ears more closely.

If it doesn't work well enough, then it will be the new Newton—and even then, here we are 20 years later, and tablets are cool.
