Well, I have used a lot of phones and smartphones. I was in possession of the original XDA (first Win Mobile smartphone), had Palm Treos, Palm Pre, iPhones and my share of Android Phones (SGS3, Nex 5 and now the 6P).
While I do enjoy Google's products, I am always in favour of a wide variety of possibilities to choose from, when I buy a phone. Therefore I hope that Google does good with their Pixels, I do hope that there will be more competitors, because competition is good for us, the customers. Competitors drive each other's efforts high to outrun each other in the chase for customers' love and they put pressure on each others product's price for the same reason.
Without competition the prices would be higher and the products would be worse.
my 2 cents
