Apple finally added multitasking to the iPad with iOS 9.0, but unfortunately not all models support the new features. The iOS 9 multitasking features include:
Update: The iPad Pro and iPad mini 4 support all multitasking features.

- Split View: This allows iPad Air 2 users the ability to run two apps simultaneously, side-by-side. (Supported Devices: iPad Air 2)
- Picture in Picture: Use FaceTime or watch a video while using an app or Safari. (Supported Devices: iPad Air, iPad Air 2, iPad mini 2, iPad mini 3)
