The Great Start of Apple's iPad
The results weren’t all bad though: Apple sold more than 17 million iPads from April through June, beating its own as well as many analysts’ expectations. Overall, the run the iPad has made since hitting the market in April 2010 is pretty remarkable. As of June 30, Apple had sold 84 million iPads. It took the iPhone 15 quarters to reach that number.
