Apple Highlights Its Services, In Nod to Wall Street 

For the first time, Apple put a number on its user base: In the past 90 days, Apple said, roughly one billion devices – including iPhones, iPads, Apple TVs, Apple Watches, Mac computers and iPods — connected to services such as the App Store, iTunes Store and Apple Pay. Those one billion devices generated $5.5 billion in services revenue for Apple during the three months ended Dec. 26, an increase of 15% from the same period a year earlier.
