> What's not so easy is to try to text someone with one hand or browse the web with one hand.
I've used phones of all sizes, and I've never found one where it is easy to browse the web or text with one hand. Sure, on a phablet, its too big to hold comfortably and do that, but on a tiny old iPhone, its too small to type accurately one handed, have enough of a viewport to see enough of a webpage to be worth browsing on, or accurately hit links one handed. So, even with a tiny phone, it ends up only really being convenient to do those tasks two-handed, and then what's the benefit of the miniscule screen?
