Keep in mind android they bought, then the leader of that project "resigned" for sexual harassment. So it's continuing but I doubt it'll be more than incremental improvements, as we've seen in the past 5 versions.
But I think Gmail and Maps were fairly innovative products when they came up. Both in terms of "wow I didn't think this would be possible before" and being viable businesses.
I use iOS, and have no love for Android but... that's an insane statement.
There's almost 3 billion android phones out there, and one guy leaving isn't going to cause Google to throw up their hands and shrug. Phones are just really, really good now, and there's not much you can really innovate on.
