Siri processes 1bn requests a week (& more Apple stats)

"The company reported that its App Store has crossed 100 billion app downloads, with $30 billion being paid out to developers so far.
In terms of adoption of its latest software, Apple claims 55% of all Mac users are running on OS X Yosemite while 83% users are running on iOS 8.
Apple made major announcements for its digital assistant Siri this year and claimed that it serves up 1 billion requests a week and is 40% faster and more accurate compared to last year.
Maps is the other Apple service that is getting great new upgrades with iOS 9, with the company claiming that Maps was used 3.5 times more than the next leading maps app with its service getting over 5 billion requests per week.
Apple Pay, the company’s relatively new mobile payments service is now supported by 2,500 banks with there being over 1 million locations where consumers can use the service.
iOS 9 isn’t as major an update as what we’ve seen in the past. Instead, the company is working on ways to make it faster and more powerful. Apple claims iOS 9 offers a 50% reduction in CPU usage while drawing while an iPhone 6 running on iOS 9 lasts for 1 hour extra in a typical usage scenario."
