I'm an Android fan. I estimate that 90% of the people I interact with on a regular basis (friends, family, co-workers, etc) have no idea what a Nexus phone is. I've shown them my 6P and while many of them think the screen is great, it takes nice pics, and is aesthetically pleasing, only a handful had even heard of Huwaei or Nexus. Some even thought it was a Samsung phone.
Everyone knows Google. From my four-year-old niece to my 68-year-old coworker, I probably don't have an acquaintance who is unfamiliar with the Google name. That's why I think the Pixel can be a success. If I go to a party and ask if people want to check out my Google phone, I'd bet I'd have way more people interested than if I said check out my Nexus 6P phone. Name recognition is a big deal, especially when it involves something as personal and essential as a smartphone.
Yes, the Pixel is pricey, especially from those of us who come from a great-bang-for-the-buck Nexus 6P. But I'd be interested in it if it does what I hope a flagship phone is supposed to do:
1. Gorgeous display.
2. Fast AND reliable (battery doesn't explode, etc).
3. Camera can quickly take great looking photos.
4. Has "cool" features (Google Assistant, VR).
If the Pixel can do those things, I think it will be a success and will generate interest for future Google phones.
