Hi, welcome!
I can’t talk about reasons for you to consider getting a Fairphone because I don’t know what’s important to you but here’s why I bought mine:
- Repairability: Modular phones are the most repairable, and FP even sells replacement parts for reasonable prices.
- Sustainability: I like my big purchases to be about more than just money.
- Open Ecosystem: I moved from an Android device without an (easily) unlockable bootloader, but this applies doubly for Apple products: Closed ecosystems are anti-consumer.
