Last week at WWDC, Apple's developer conference, Apple introduced major changes that will be happening with the operating systems of Macs, iOS devices, and the Apple Watch. Apple immediately released developer betas of these operating systems, and the tech pundits have already put the betas through their tests as they begin optimizing their apps to run with new features embedded in the code.
The number one comment from tech pundits is, “The iPad will become a real device with multi-tasking.”
The main feature causing this reaction in iOS9 is multi-tasking. iOS 9 allows apps to run side-by-side (only on the iPad Air 2 or newer), to use a feature called Slide Over to quickly check something in another app, or to open a video and play it in the corner of the screen.
Some quick thoughts: you can already use split screen on Samsung and Windows tablets. On my Windows tablet, I seldom use this feature, and I wonder how much others use it. Second, Slide Over is not much of a labor-saving maneuver than a quick four-finger swipe to another app and back, something you. An already do on your iPad. Finally, watching videos while you work has never made anyone more productive.
No, I'm not mad that Apple added these features. I will be happy to install them and try them. They represent a nice improvement (as will the ability to use the on-screen keypad as a trackpad for editing text), but none of these features suddenly makes the iPad any better of a solution versus what it previously was–and chances are the feature you want to try most (split screen) won't run on your iPad! Most schools are using 2nd and 4th generation iPads, and not all of these features will run on those devices (although I believe that iOS 9 itself will be able to run on the iPad 2).
While every version of iOS has a few bugs (most that get worked out over time), each version brings some new features that make the experience better. But the biggest impact on the usefulness of the device are the apps that you run, and the functionality/usability of those apps themselves. Logically, most iPad (or Android) apps are not as functional as programs on Windows and Mac operating systems. And if you try to make an iPad into a full-blown computer, you will never be happy.
I have had a lot of success using my iPad as my primary device, and I don't have many complaints. Continual refinement makes my experience better, but it doesn't “finally make my device useable,” as it was already my primary device and has been for 5 years.
