It’s great. I’ve been using it all morning to get around. It’s worth it for the clearly superior place search functionality alone.
Judging from my inbox/replies/etc, it seems like a lot of folks expect me to take a shit on the app. I’m not going to do that. As I’ve always said, my only requirement to use something is that it be the best. And that’s clearly the case here.
Google Maps is superior to Apple Maps in most (though not quite all) ways. And I’m excited to have it back on the iPhone. I’ll be using it constantly.
