Google today announced via Google+ that it is now offering accessories for the Galaxy Nexus through its Google Play store. Only three accessories are offered so far: A vehicle dock, the HDMI Portrait Desktop Dock, and the Desktop Dock with Pogo Pin.
Accessories only support the HSPA+ version of the Galaxy Nexus (the same one that is sold on Play).
Like the Galaxy Nexus, the accessories are only available in the U.S. although Google has indicated that it will expand sales to other countries in the future.
