Google glasses are a new form of a wearable computer. It is basically just a computer that u put on your eyes another type of a smart phone but just a more fancier version. This is probably the direction that technology is heading as people care more and more about fancy technology and will buy them more than others. These glasses and watches are basically something that looks really good but can actually do the same thing a smart phone or a android.
Some benefits of having these technology is to know what your doing and what is needed to be done with a computer next to you. The con sides to these objects are privacy. You are basically telling your location every where you go. There would be no privacy left as people will just message you wherever you go. People will not be able to enjoy an hour or two of no one bothering them with the increase temptation of these technology that leads to no privacy
