1. Has to have a light to indicate recording, or everyone around you will be paranoid. (Most people will still be paranoid, but at least you can say "No red light, it's not recording!").

2. Will probably be very popular as a cyclist camera. Cyclist who just want a decent 720p camera to record cycling activity (evidence against dangerous drivers), but don't want to attach a dorky camera to their head (i.e. GoPro), will like the Google Glass -- assuming it can fix onto cycling glasses. Also, having GPS/Strava/heart-rate/cadence all on your Google Glass will be awesome for cyclist. (and runners)

This whole light thing seems a bit out of proportion, like being paranoid of people wearing shades in case they are eyeing you up (which is more than half the reason anyone wears them in the first place).

I recall reading that a lot of women wear sunglasses so that you can't make eye contact with them, as a lot of men use eye contact aggressively.

A goPro mounted like an alien beacon on top of the rider's head could be a clear signal to a-holes that their behavior will easily be recorded. I could see a whole secondary market in decoy helmet mounts appearing. Google Glass might just inspire more rage since it lacks the goofiness. Drivers may get a sense of levity from the goPro. It's like seeing the antennas on little cars that make them look like remote controlled cars... so cute - "Go ahead. Cut me off. You're just the cutest little two seater I ever did see!!"

You can get (kids!) helmets with built in cameras already. When the UCI drops their helmet cam ban then we'll see some good pro ones.

Strava already has a Glass integration they showed off at the last Glass dev demo.

The Recon(?) cycling augmented glasses look pretty good too.

As if the NSA won't be able to turn on the camera and microphone any time they want, without turning on the warning light. Riiiiiight.

There is a reason why the GoPro is still in the form factor it is in. It is terribly hard to pack most of the GoPro's features into a small volume, they went with something cubish and built accessories off of that. The Glass couldn't keep up to the demands many fans would have and I imagine there is a struggle within the company concerning the increasing demands for resolution, frames per second, and image quality with the volume of the form factor they have.

That said I do see helmets with HD cameras and wireless controls in the future. Trademark™ and all that.
