True, thanks for the correction. Fixed me post above.The $200 jump is more like a 33% increase than 20%. The thing here is the Air 4 itself has gotten very close to iPad Pro territory. There's much fewer reasons to pay the extra $200 now than there was the $300 for Air 3 to Pro.
I agree about the $500 threshold though.
I think the $200 extra is still easily worth it. For that, you get a slightly better screen, double the storage, FaceID, and better cameras. That’s a lot of extras (esp compared to Macbooks where $200 barely buys a RAM upgrade usually, hah). And since we’re already north of $500, the extra outlay is not as significant.
