If you must buy a Pixel, don't get one from Google's Project FI
I have five phones from Google (2 nexus, 3 pixel) and was one of their biggest fanbois, primarily because they put out crapware free phones.
I currently have two broken FI pixels (broken hardware) and one working one. (along with a couple of Nexus phones).
Still paying on the three pixels, all are under the (extra cost/month) hardware assurance plan.
I can't get them fixed despite paying the extra hardware assurance simply because i put a TMO sim in them instead of a FI sim (doesn't void warranty or anything, just doesn't register in their system then, and they can't get past that). I eventually wound up purchasing lower end Samsungs just so the kids had phones and have largely given up fighting with them over this.
I'm done with FI, and likely done with Google's hardware as well. At least if i buy cheap off brands i know better than to expect actual resolution to issues.
