Why is it important: When Apple unveiled iPadOS 16 at WWDC this week, it showed off a ton of features. However, since Apple’s business is to sell its latest and greatest hardware, it has somewhat shrugged off the full compatibility of its latest tablet operating system with older iPads.

According to Apple good print, iPadOS 16 is compatible with “iPad (5th generation and later), iPad mini (5th generation and later), iPad Air (3rd generation and later), and all iPad Pro models.” That’s a pretty decent range for an advanced OS. However, it’s also a little misleading because some of its most exciting new features are only compatible with tablets equipped with the M1 chip, which excludes any iPad released before 2021.

It’s not unusual for an OS to have features that don’t work on older hardware. Obviously, many features will be specifically designed for upgraded systems. Some of the best features of iPadOS 16 are meant to drive sales of the iPad Pro and the upcoming iPad Air M1. If you’ve already considered upgrading to a more expensive iPad, here are the features you can only get with the M1 models.

The stage manager we coated previously offered advanced multitasking features only on the iPad M1. Stage Manager is also closely related to the plug-and-play external display support that Apple has demonstrated. So if you were hoping for any of these features, you will have to upgrade. Of course, AirPlay is still a viable option for those who want to use an external display.

Even more limited is the reference mode. This feature allows iPad Pro to meet color requirements for color grading and compositing, “where accurate colors and consistent image quality are critical.” It can also be used in Sidecar, turning the tablet into a second reference display. However, Reference Mode will only work on the 2021 12.9-inch iPad Pro or newer.

Some accessibility features are limited to certain models, including Detect Mode and Magnifier Door Detection (iPad Pro 2020 or later). Virtual Memory Swap can use up to 16GB of your iPad’s memory as virtual RAM for resource intensive applications. However, only the iPad Pro M1 and iPad 4 (256 GB model) can do this.

Unfortunately, some of these options exclude most users, even those with relatively new hardware. However, all models from the last 4-5 years support most of the other new features. Check out the iPadOS 16 WWDC section posted above for more information.
