In April 2012, Google introduced Google Glass, augmented reality glasses. Now the time arrived to open the pre-orders for the first commercial version called Explorer Edition, at the cost already planned of $1,500. For common users it will take a long time before they can buy them, howver there’s the possibility to become an Explorer, meaning being part of a group of “pioneers” who will participate in the Google Glass launch events in New York, San Francisco and Los Angeles.
