Android has come out with a pretty clever marketing tool in the form of Andy pins. As you can see in the picture, Andy takes on various outfits and scenarios and is in pin-form, waiting to be collected by his fans. The MWC was crawling with various pins that people were steadfast in collecting and trading.
Some, of course, are more rare than others, but above all, people have been going crazy for them. According to the Wall Street Journal, there are approximately 86 different pins out there. I just checked ebay, and haven’t found any yet. Let us know if you see any in the wild!
