My thoughts on the Google pixel 2 .
I dont see a reason to upgrade from the first google pixel , but if you are coming from another phone it may be a very good investment due to the great camera , google assistant ( which is the best by far ) , and unlimited storage of photos and videos taken from the pixel.
The pixel + google fi might be the best travel phone due to the fact that it works with 4g in 135 countries at the same rate of $10 per gig. If you do all your communications thou data then you can travel the world and keep your posting , chatting , and talking for the same price you would pay in the USA also the pixel on google fi is also able to auto detect safe open wifi and seamlessly switch to it even if you are in a call.
No service or phone is perfect but Im surprised there is not more news about the Pixel and google fi amongst world travelers from the US. https://fi.google.com/about/
