Two things:
1. He's held / seen the phone live, I buy online so won't get a chance to before I decide.
2. He's also held hundreds (thousands?) of phones which I haven't.
While he does have preferences that differ from mine, his perspective is still interesting.

Valuing someone by reach makes no sense at all. Most professors at MIT have no social media reach at all, I still value their opinions extremely highly.
In fact, valuing someone's opinion purely based on the size of their megaphone is partly why we're the world is in such a bad state politically (and in other ways) these days. E.g. people listening to social media influencers opinions on vaccines.
