Considering Snapchat revealed Spectacles, which in my mind was an unexpected hardware development, they could use funding for side projects and expansion. Hopefully, they don't become like Twitter and waste all that money for so little gain.
I think that they should be marketed as "cool glasses (that also record video)" as opposed to "video recording glasses". "Video recording glasses" are a gimmick, "cool glasses (that also record video)" could be timeless.
I think that people will be more likely to wear the spectacles for this reason--they can actually pass for a pair of somewhat ostentatious sunglasses to an unknowing observer because of their near-symmetry, vs. Google glass, the mere shape of which screamed "BORG!"
The merger of fashion and technology is possible, considering the existing fanboyism of some products and design of smart watches.
I'm surprised their hasn't been nearly the same adverse reaction to spectacles as there was to glass. Maybe we haven't seen it yet as they haven't been released, but people hated the potential of Google Glass sharing pictures and videos of people without them knowing. Maybe we've changed as a culture enough in these few years.
A potential weakness of Spectacles as a product is that it augments only non-selfie, "extraverted" photography. So it doesn't engage the selfie obsessed side of the userbase as much as the phone-based AR filters do.
I haven't been a fan of Snapchat, but now I'm curious to see how users react to this product.
So the real question is more has Snapchat and its functionality built enough of a cachet to be valued as highly as something like a Ray Ban.
I do wonder about whether people will find the video-recording-and-sharing aspect creepy. It might help a bit that people don't associate Snapchat as "instantly on the web forever" compared to other services. We'll see.
