Their spectacles is going to be a game changer. I hope it does well (buy also part of me hopes it does not for the sake of everyone's privacy in public).
Naysaying Snap is fine, but not if your argument is "bullshit hype".
GoPros are a convenient, high-quality, expandable memory camera that creates a regular video file as big as the storage space available that you can use however you want.
Spectacles are a convenient, unknown quality camera creating a ten-second video that requires smartphone interaction, is designed to be on your face, and is tied to one specific (albeit popular) platform.
Aside from both being able to take video and being easy enough to carry around, the products and the target markets don't intersect perfectly, so it's hard to predict one's success from the other.
This is certainly no predictor of absolute success, just an element of understanding the potential market.
I really dislike the asymmetry between the ability to take pictures of anyone in public easily (assuming spectacles or an equivalent comes out), with low chance of detection (unlike cameras/phones, which are harder to disguise) while being unable to as easily wear a mask in public to preserve some semblance of anonymity. Anti-mask laws exist for a variety of reasons, some of which I am fine with (e.g near banks) and some of which I am not (e.g abuse to shut down things like the Occupy movement). I would like to see a similar treatment of devices like this (spectacles, google glass, or whatever other product people work on in this space).
They should be treated on par with hidden cameras and the like. Until legislation takes care of this, I am not happy with the situation.
Hidden cameras (not terribly well hidden cameras, but hidden nonetheless) are nothing new, the Snapchat innovation is to reverse the camouflage to create completely different usage patterns.
If the Snapchat specs become popular there will actually be a knockoff market for fakes that don't even have a camera, because imitating just the recording status lights will be enough to get the "say cheese" effect.
