No, Google Glass is not the "Next Big Thing" as Glass is little more than a tech toy at the moment. Though Google claims it will have tons of functionality, all I presently see is a pair of glasses that can check email and take pictures. Using a smartphone seems to be easier and have more functionality.
Google Glass solves a problem nobody knew they had. Before it was introduced, people were not looking for a computer in their glasses. Glass is a cool piece of technology, but it costs $1,500 and it looks really ugly. People don't want to buy something that makes them look worse, especially when it doesn't have any real advantage over a top of the line smartphone.
