not me. I did use my dad iPhone 7 plus for one day before giving it to him. love the thinnest, battery life, and camera, but can't stand ios. the notification system can't touch Android N. all I can say is, all these pixel bashing sounds very familiar to last year when the 6p was announced. most ppl are writing it off before reviews come out or using it themselves. so far, most ppl who have played with the pixel really think it is a good phone. I personally am excited about Google assistant and the new camera speed. I can almost guarantee you we will hear the same thing next year how everyone will say the pixel is awesome, and pixel 2 isn't worth it.
edit: my wife is a long time iPhone user since iPhone 4, so I have experience with ios for much longer than just 1 day. previously I had to use it for a full week before I got a replacement phone, and did not enjoyed using it.
