Apple’s iPad announcements – with multitasking being, in my mind, the most profound one – revolve around doing more with apps without relinquishing control of the experience. iOS 9 on the iPad will be able to display multiple apps at once, but you won’t have to use two apps at the same time if you don’t want to. You can swipe with two fingers on the keyboard to control the cursor and speed up text selection, but it won’t become the sole input mechanism of the iOS keyboard. Users of external keyboards will get the ability to Command-Tab through apps and view cheatsheets for shortcuts, but, of course, iOS will remain perfectly usable without a Bluetooth keyboard.

This, I believe, is an important distinction to make when assessing the iPad’s adoption of features that have been exclusive to desktop computers. The iPad’s improved capabilities in iOS 9 are options – deeply integrated with the operating system through gestures, but, ultimately, not the default way to interact with apps. Compare the new iPad multitasking to OS X: when you launch an app on the Mac for the first time, it defaults to window mode without taking up the entire screen; in iOS 9, iPad apps will launch in full-screen as usual and allow you to view a secondary app only when needed.

And:

The iPad is on the cusp of becoming a completely new computer. This is not an overstatement. Anyone who uses the iPad enough has known for a long time that the device could be capable of a lot more, and iOS 9 is Apple’s answer.

Last night, I was watching John Gruber’s live interview with Phil Schiller on my iPad, and I realized that I wanted to read people’s reactions on Twitter. I instinctively reached out to my iPhone, because that’s what I’ve been doing for years when watching live events: my iPad plays video and I use Twitter on my iPhone. Not anymore. Thanks to iOS 9, I put The Talk Show’s video player in a floating popup, opened Twitterrific, and continued watching. When I wanted to take notes, I swiped from the right edge of the screen and I started typing in Notes – all while still watching the video and having Twitterrific open at the same time. It all felt natural, and it was glorious.

This is a great read, gets right to the heart of the matter.
