Much will depend on the apps developed for it....or "Glassware" as Google is calling it. So far, they seem geared for the consumer space...CNN announced news alerts this morning. Elle magazine is doing an app although none of the apps can contain ads. And there another social app called Ice Breaker, according to a NYT story.
So the consumer space seems where the device might get traction although let's face it: consumers would not pay $1,500 a pop, which is what developers are paying for it.
We'll see if the enterprise apps start appearing. Some CIOs have said they envision Glass having applications in retail and engineering.
