Augmented reality (google glasses)

What I know: I think the Google glasses are a tool that can be used as a camera that tapes what you see, also it may have a connection to internet because is of Google.  

Questions: 1- There are going to be for public sale, if yes what will be the price?

2- When are they going to be launched?

Things I Learned:

1-    The glasses are going to be launched on 2013 to Developers in the US; in 2014 they are going to be for public sale.

2-    The cost of the glasses will be around the 1500 dollars.

3-    The materials the glasses will be made are a transparent LCD or AMOLED display to put information in front of your eyeballs

4-    Google Glasses are a cellphone in form of glasses, it tells you the temperature, you can video chat, make an appointment, hear music ext.
