Still don't see the issue. There's a bunch of Apple devices released every year. Would 1-2 months gap between releases really make that big of a difference?
Personally, I set aside funds per paycheck for entertainment expenses (including tech) and I just work off an annual budget. Besides, I don't need to buy every single device that Apple releases and I certainly don't need flagships in all product categories.
That's true, but it's not just a matter of money. Some people who might have bought the Air 4 just because it's the new shiny thing are going to lose interest as soon as they see the newer shinier iPhone. When the Air 4 had it's time to shine all anyone could do was look at pictures and view pricing on the website. Kind of feels like it will be overshadowed when it's finally available.
