I'm a phone nerd/hobbyist so I usually upgrade every year whether its iPhone or Google branded phone and use them for daily drivers. The upgrade from the Nexus 5 to 6P was initially beneficial to me based on bigger screen and better camera. I started to get annoyed at the battery life and size of the phone (I thought it was on the big side, obviously smaller than the previous Nexus 6). Although more expensive, the Pixel XL fixed those issues and is still a 0 issue phone in my daily experience. My only nitpick on the Pixel is the low level headphone jack and ear piece audio output compared to iPhone which is same with every Nexus i've had.
During the google presentation I pre-ordered the Pixel XL 2 out of impulse with the trade in offer. Later that night I thoroughly thought about it, I really wanted a smaller phone with slimmer bezels and the regular Pixel 2 doesn't offer that. The Pixel XL 2 seemed nice, but it's still a bigger phone and is it really worth the $700+ upgrade? (XL2 128gb + preferred care + tax - $410 trade in) I have little to zero problems with my OG XL, I'll still get software updates, so I ended up cancelled my preorder the next morning. Now i'm really thankful I did. Let's see what next year brings.
