The Pixel is by no means a bad phone, it's just been an exercise in disappointment the whole way. So I'm not actively planning to switch phones, I'm just lamenting that I don't get the same utility out of the Pixel that I was getting out of my Nexus 5. Also being on Project Fi locks me into a certain set of phones, switching would be an expensive endeavor.

The Pixel is so solid, and still plenty fast enough for me that I honestly can't imagine upgrading until there's something I need that doesn't support it.
