Talking about multitasking features, Apple iPad 12 has a split mode 1/2, 1/3 or 2/3 to 2 apps tied up simultaneously, moreover each app itself can also open in two different windows to compare the content (like two parallel Safari web, two parallel document pages). The source added that Apple had shared plans to launch it last year, but the plan was postponed. The Sooner the WWDC 2015 conference to be held in June, Apple revealed it for people to know more about it, and most likely these are the hallmarks of iOS 9.
The multiuser feature is like on Mac, Windows and Android today, which is that each account will have their own app and data. Another person cannot access the other account, suitable for use in businesses, schools where many workers and students can share one device.
