As an Authorized Retailer technician having the back glass be replaceable is so nice. For the older models we just replace the whole frame the glass is attached to rather than only replace the back glass so it makes repairs not only easier but something that can actively be done at our store(as we dont keep frames in stock).
Technically most of the weather data is derived(within the United States) from the National Weather Service, all of this data is a matter of public domain under federal law(so it’s being subsidized by taxpayers). What companies like the weather channel or accuweather can do is increase the accuracy by adding more stations and providing more compute power to run more powerful simulations(something the NWS can’t do because of budgetary constraints) or what an app like Carrot can do is allow you to add your own weather station and interpret the data to give predictions.

The current closest thing for tap to pay for consumer to consumer payments is NameDrop then using Apple Pay Cash through iMessage however this is a less seamless method and is only available in the US. I can however see Apple expanding the tap to airdrop features to Apple Pay Cash in the future, perhaps with iOS 18.
