Surprised more people haven't mentioned the difference with respect to speakers. If you plan on using it for any video content you really will appreciate the Air's true stereo speakers top and bottom versus the dual speakers on the iPad 9 that fire only from the bottom.
The stereo speakers were already mentioned in the 2nd post. No need to bring it up over and over.
And if the Air does get updated soon, I don't think you will have any buyers remorse as the changes should not be drastic.
Agree on this point. Based on the mini 6, the Air 5 shouldn't be a significant departure from the Air 4. Depending on release schedule, probably just A15/A16, Center Stage, back LED flash and 5G. If it's A15, CPU performance is practically the same as the A14. Main difference is just GPU.
