Weekly note ✏️
“Love is in the Air…” — that’s exactly what came to mind after watching the latest Apple Event.
We got updated AirPods Pro 3. Making them the second device to measure heart rate after Apple Watch. There's a new generation of Apple Watches with an emotional promo featuring real people sharing how the watches saved their lives.
And of course, the main product - the iPhone 17, with upgraded cameras, the ultra-thin titanium iPhone Air with dual cameras, and the iPhone Pro with triple cameras.
What stood out: there was no iPhone 17 Pro Max promo or video this time—just plain text. Another interesting twist compared to last September was that new devices weren’t just showcased at Apple Park but also in Apple Stores across the US, from San Francisco to New York.
Most of the lineup will be available later next week, so if you’re planning an upgrade, now’s the time. 📱⌚️🎧
