I posted nearly the same reply to the other "you gotta use OSM!" thread a few weeks ago.
Completely unusable as a replacement to apple or google maps, for me. Might be OK for looking for roads, like, uh, a street map - but to replace gmaps functionality with the simple feature of "click on an icon and show me the details" it is not.
Not intuitive, but zoom in and hit the edit button. You should now see all the data as vectors. Click on anything and you will see all of the metadata.
If I see a place on the map.. Why can't I click on it? I can't get the address, telephone number, website etc.?
And I see and picture of a shopping basket? What is it? I also see a cocktail glass, it's a fucking mystery.
