That’s my opinion, I think that the Google Glass is far ahead of its time currently in 2013.
Apple and his products are declined day by day. And I don’t think so that the iwatch change anything relative the android power.
The Google glass challenge and futher the Iphone (phone, music, photo, video, mail etc).
But, The google glass is for the augmented reallty. Even if this concept is been in control, because the augmented reallty is a concept not a technology, in our cities the augmented reallty is not the standard. May be, it will become the standard in our connected cities.
There are many drakes about Google Glass. How many people wear or use classic glass? How this people coul used the Google Glass and them classic glass too? It’s will be complicated.
Google is a pioneer, but the Google Glass far ahead of its time.
The device are becoming more power and more small. Example: PC became a Pad (tablet) and smartphone will becoming a watch like Biiwatch for a few functions for the time being.
