I didn’t find the event that exciting. No new hardware “must have” features, except perhaps the A18 chips to enable even faster (20-30%) “Apple Intelligence™️”.
A bunch of current devices (*) will also support AI™️ at launch, including the iPhone 15 Pro and iPhone 15 Pro Max and all M1 or greater iPads and Macs.
And I’ll wait to see how much it improves things like Siri, but I dearly hope it doesn’t just end up becoming an intrusive annoyance that I wished I could disable, but can’t (this is still Apple after all).
