Honestly, once you have a solid screen (perhaps OLED, but excellent LCD at best), solid touch input, solid wireless networking, a decent camera, good materials, fast performance, a Secure Element with Fingerprint Sensor, NFC payments, USB Type-C with Power Delivery, good battery life, and perhaps even Wireless Charging, it would take something truly transformative to win me over.
I realised some time ago that with USB Type-C in particular laptops had gotten “good enough” for me and that I vastly prefer the boring but solid and repairable nature of my personal ThinkPad X270 that I bought used and upgraded with a Smart Card reader, NVMe storage, and better display, than buying a new MacBook Pro.
Fairphone is one wireless charging module, removal of the front text, and more subtle back text away from being the phone I would replace my current iPhone X with when it eventually dies, just because it seems to be a solid and repairable implementation of everything I want. I would miss the OLED display and general niceness of Apple’s hardware but even though I can afford an iPhone 11 Pro, I just can’t justify it anymore.
(As an aside, I would have to figure out my Apple Watch situation but that’s a different lock-in story. )
I don’t really want a phone with three cameras, just one that meets the “nice enough” bar and meets my needs, repairability is a bonus.
Maybe I am just getting old.
