Just had my brother in law show me a concept phone where you just put in block modules for the things you want and need in a phone. Want more battery? Take off your camera block module and plug in more battery block modules.
Obviously the concept as presented is near impossible to achieve. I told him That and said we can get close. I showed him framework laptops that are trying to achieve the very thing he wanted (to a certain extent). He said that if they could make that a phone he would switch from his apple ecosystem in a heart beat. The ability to swap for a bigger speaker on the fly for get together's and parties was tantalizing (big music guy).
Just interesting because even non tech people want this when you sell it to them properly. They don't actually want a walled garden ecosystem that is "simple".
