I'm thinking that myself with the N5X now... Really impressed with it, and the camera really is great (been using it with Manual Camera), but even after I did the case comparison I keep thinking about the 6P.
Argh! Agonising like a rock star lying in bed at night, wondering whether to release that difficult second album...
Same here really. Like the 5X a lot but feeling like I bought a BMW M3 when what I really want is a McLaren P1. One of those things... I might have to actually buy an N6P to know whether it's right for me over the 5X.
