It is the iPhone of Androids.
Jokes aside they really talked about the camera a lot so waiting for its review. ( I saw the whole event live
)
Other special thing is inside the software which has Google Assistant, it is kind of a AI. It was exclusive to Pixel at firt but now someone at Xda has made it possible for Nexus 6p somehow so it doesn't look like some special feature now.
To be honest it is a really good phone but price a lot higher. Nexus line was famous mostly for its low pricing which is dead now.
