Besides of Nexus 7, in Google I/O, they announced Nexus Q. That is a kind of entertainment center. It can connect to TV and speakers. It sounds like an Apple TV killer! Well, that has more functions! It can controlled by your Android phone and Tablet. In addition, it can do social streaming. It's cool!
Moreover, I love that sounds quite creative. It is not in a box, Google turns its new product into a Sphere! It looks fresh!
But that is a bit sad, it only can be pre-ordered in U.S. for $299.
