As stated before, we wanted to use the data that is already there and make it available in a userfriendly way, something the current geocoders for OSM don't really do.
When you talk about the claim I make, that I wish OSM is going to be the first goto place when people want to search something on a map is still valid. It's my wish, not a general statement I'm making. And hey, it worked with Wikipedia. For many people it's the first place they go to when they are looking for information, so I think this can also work for OSM
When I need to look up stuff I usually go to Google Maps, too, but that's only because the OSM solutions out there frustrate me with irrelevant results and I have to scroll through endless amounts of data to get to the information I'm looking for. :)
Apple didn't really use OSM. The current OSM is pretty good, by the way. It's just a pity some data is still wrong (for example, many postcodes in Madrid, ES).
