The rear camera on the Nexus 5X seems rather excellent. Very very good in low-light situations with those largish pixels and the High Dynamic Range feature of the Google Camera app.

The size and weight of the device are very nice -- a lot lighter in the pocket than the 1+1. Being about 1/4" narrower, it is easier to hold in the hand as well.

Definitely a very good upgrade except for the smaller amount of built-in flash. Thankfully, USB OTG works just fine with CM13, and the tiny little Sony USB-C/A stick I purchased works more than well enough for backups and file transfers.

The USB-C connector is a win, but also a nuisance given that the phone, charger (and aforementioned USB stick) are the only USB-C items in the house. I did also get a Belkin USB-C/A cable though for use with ADB and data transfers.

Pleased.
