As for the $400-$550 price range you indicate are willing to pay for Google’s computational photography genius wrapped up in a midrange package, it somewhat clashes with the rumored price tag of up to $600, so we’d have to wait and see.
Ever since Google’s experimental Nexus phones sold at or near cost to spread the Android cheer far and wide morphed into the flagship Pixel line, the situation with pricing began to go south. We are now at the moment when Google asks for its latest somewhat underspecc’d cell phones a starting price of $800, and is now in the “thousand dollars phone” club with the 128GB Pixel 3 XL.
Granted, these two puppies carry one of the best mobile cameras around and are a traveling exhibit of Google’s computational photography chops that started it all. Still, not everyone is into snapping pics and comparing the results with the iPhones and Galaxies of this world as we are, while the rest of the specs leave something to be desired at that price.
