The main problem with abandoning Google is all the services associated with it, not only mail. And paid Gmail continues to offer mobile sync, which FastMail does not.
Yet, FastMail looks quite nice.

The other thing I forgot to mention in the post is contact syncing. I'm honestly not sure if I like the contact pollution gmail does more or less than not having sync between FastMail and my phone.
Do you know if there's any plan for them to release an android app that would let my phone sync?
And I do realize the irony in trying to cut out google while using an android phone.
I use K-9 Mail on Android with Fastmail. They both support IMAP IDLE, so you get immediate push notifications of new messages.
You can set many alternative login passwords in fastmail and the google auth is one of those.
So with the google auth you use your google auth fastmail password and append your google auth login so if your password is Password1, when you login you would be typing something like Password1123456 to login.
You can also set other login passwords for applications or imap with or without delete capabilities but a lot of the time they need full permissions to work with email clients, it could be nicer.
