It's nice to see Google totally nail the hardware and overall experience. The camera sounds impressive.
The problem for me is that the $700 phones aren't twice as good as the $350 phones. The midrange (or low-high-end) has got good enough that I can't justify doubling the expense.
I've got a LG G4 with a faulty mic due to water damage. If I can't repair it I'm seriously considering buying another one because I can't see anything else as good at that price point and nothing that makes me want to spend more.
