Apple’s recently released quarterly earnings report mentioned that they had 1.5 billion Apple devices active in the last quarter. It is foreseeable that the scale of the Apple ecosystem will soon exceed that of the Windows ecosystem.
They mentioned this in detail in the report: “We are thrilled to report Apple’s highest quarterly revenue ever, fueled by strong demand for our iPhone 11 and iPhone 11 Pro models, and all-time records for Services and Wearables,” said Tim Cook, Apple’s CEO. “During the holiday quarter our active installed base of devices grew in each of our geographic segments and has now reached over 1.5 billion. We see this as a powerful testament to the satisfaction, engagement and loyalty of our customers — and a great driver of our growth across the board.”
