70,000 per day are tablets that are purely based on Google’s platform. Burnette notes that Apple sold 17 million iPads in its most recent fiscal quarter, which works out to 188,888 iPads sold each day, on average. Divide that figure into the 70,000 Android tablet sales number and you get 37.2 percent. That’s a big jump from 14 months ago.
