I have a pair, and while I haven't had much time to experiment with it yet, the little bit I have done, I think they got several things right. 1) The 'viewport' is out of sight if you're not looking up and to the right. This gives it the non-intrusive aspect that allows someone to wear it while engaging in everyday activities. 2) The 'pairing' with another Android device I think allows the developer to leave heavy computation / work off of the small Glass device to conserve battery. 3) The form-factor. I think it's very lightweight, and again non-intrusive aspect that doesn't make it a burden to those who don't already wear glasses. I haven't dug in deeply recently, but originally I had the sense that there's not enough integration with popular 3rd party apps. Engagement from Facebook, Twitter, Snapchat, etc. would probably help with adoption, though the pricepoint is definitely something I see most people struggling with. Perhaps tight integration with things like Google Apps might make it appealing to small or larger but agile businesses. I think this could be both a consumer and business play in terms of adoption, though I think the path to business adoption may be more straightforward in terms of the kinds of apps that would need to be developed. I can imagine alot of really interesting things might start happening once Google has made Tango available for mass adoption. https://www.google.com/atap/projecttango/#project Let's hope they don't shut the door on this too quickly. The idea is so new and different that it could take some time before folks really sink their teeth into how it can be used where there's real value to the consumer / business who is going to make the investment.
