Continuing the discussion from What about a smaller Fairphone?:
Since FP2 has got loads of pluggable parts, does that mean it’ll be a lot easier for you to produce a bigger screen and case?
I’ve got big hands and I’m now old enough that my eyes are slowly degrading and I need reading glasses 
so a bigger screen would be fantastic! otherwise I’ll be forced to get bi-focal glasses and a screen pen to operate it.
I am not alone I know. My parents can’t handle smartphones, but they do fine with tablets for the same reason. And even if you have normal size hands when you’re old, if you’ve got the DTs, those small buttons are hard to hit.
