The last year quarter was buoyed by previous quarter supply constraints causing a lot more sales in many categories and products.
It's not that this quarter was bad (it was fine) it's that last years quarter was SO GOOD and last quarter had no major supply constraints that we see this.
Basically - Apple has got so good at the supply chain it's hurting their numbers for quarters with no new releases.
But sure, start speculating about [insert your favorite phone] and writing screeds about phone subsidies/performance/innovation/whatever. It won't be right... but you'll feel better I guess.
