According to early reviews, the Pixel is now the best Android phone you can buy. However, its reason for existing is not to win over the Android market, it's to compete with the iPhone.
To do that Google is going to have to persuade iPhone users to leave behind iMessage something it's currently not in a position to do, for two reasons.
Firstly, iMessage is a feature rich messaging platform which is inclusive whilst setting very clear boundaries between iPhone users and the great unwashed. Leaving the sanctity of the pure iMessage blue bubble to become a green SMS bubble on all of your friends iPhones? It's a big step and not one loyal iPhone users will take lightly.
Secondly, there's the problem of staying power. How many times has Google shuttered services after running them for a few years? That isn't the kind of behavior that fosters a long term relationship and honestly, who can say, hand on heart, they believe Allo isn't just the latest in a long line of Google messaging platform fails?
For all that Apple offers within its ecosystem, iMessage turns out to be the glue preventing users from leaving.
And right now, Pixel or no Pixel, Google doesn't have the pull to unstick them.
