You know this discussion reminds me that as much as some don't like Purism. If they had a phone that worked well (meaning you don't have to think about power usage and heat issues), then their approach of separating the modern (M.2 slot for a baseband module) onto a daughter board makes a lot of sense ... as long as you can find or they sell a replacement.

Imagine keep the device you want just update the components. Fairphone does this to some extent, sadly I don't think the cpu/modem though.
