If you were utterly confused, like I was, how the iPad Air M4 compares to the iPad Pro M5 and the iPad Pro M4, this 3-column comparison table from Apple's website might help:

https://www.apple.com/ipad/compare/?modelList=ipad-air-11-m4...

The quick summary:

- iPad Air has 2 stereo speakers, rather than 4 speakers as Pro models

- Touch ID in top button rather than FaceID as Pro models

- iPad Air is slightly heavier (???) than either Pro model

- screen of iPad Air is a bit less bright

- no nano-texture display option on iPad Air

- no true Thunderbolt connectivity through USB-C port on iPad Air

- all devices can use same Apple Pencil Pro...

- ... but the iPad Air takes a special Magic Keyboard (supposedly due to form factor)

- camera array is slightly different on iPad Air (no ProRes video)
