Google. Activations. Counting.

What google decides to use for their numbers means absolutely nothing!
The only term here that has been defined is "Android Compatible", and guess what: By google's own definition, The Kindle Fire is indeed "Android Compatible".
Find me another document that says "only Android devices that show up in Google's activations counting can use be considered Android devices." It's a count, and it doesn't prove or disprove anything.
