I'm not aware of any mobile phone in the USA that has a light that turns on when recording (not including the flash). Glass won't have any special zoom capabilities. It's the same as a phone. If you're afraid of someone zooming in on sensitive data don't put it near a window where others can see it.

The light turning on when recording will be disabled in no time flat for people who want to record surreptitiously.

You are right.No phone has that but you can see a light in the prism on Glass when the device is recording. I am sure they can add zoom capabilities to the device.

The point is that no matter what alert signals you get, you can't just beat/accuse someone just because he is recording.It's a two-way street.

We will see.

Zooming requires an adjustable lens which will never be added to Glass. Digital zoom isn't real zoom, you can just do that with a photo editor.

Just because Glass' prism is lit doesn't mean someone is recording. They could be looking at something else.
