As far as I know, there is no other map application that does that.
Right, and that's where most of Google Maps' value is: it's really a business directory combined with a navigation system. I'm not going to look up an address for some place, I want to just search for "<business name> near me" and find all the nearby locations and pick one and go there. Even better, Google Maps has reviews built-in so you can see if people hate a certain place.
>but I'd guess that they don't apply to the majority of people.
If you think the majority of people keep business names and addresses in a contacts list, you're really out of touch.
Also, GMaps has features competing systems usually don't, depending on locality. Here in Tokyo, it's tied into the public transportation system so it'll tell you which train lines to ride, which platform to use, which car to ride in, which station exit to use, when a train is delayed, etc. It'll even tell you exactly how much each option costs, since different train lines have different costs. Then, inside many buildings, it'll show you level-by-level what business is on what floor.
I am aware of plenty public transports in European countries that you better print out those PDFs, from their website, assuming they have them in first place.
This is not at all what they were saying, and I'm not sure where you got that. What they're saying is that Google doesn't have a monopoly on business location data, so searching for a business on a competitor (especially a large one like Apple, but mostly even OSM) does just work.
Gmail, on the other hand, like any email service, is much harder to switch. Until we get mandated email address portability, like was done with phone numbers some years back.
