You're right lucb1e: OSM is definitely good enough to replace proprietary sources (aka Google Maps) for this use-case in the Netherlands...

...but the Netherlands and Denmark are the only two countries I know of where addresses data have been opened by the government (are there other?). In most other countries, this is still an ongoing fight, and crowd-sourced data is still not on par with the proprietary offering.

The good news is that we are working on it: see for instance here (in French) for the ongoing grassroots effort in France (started a few months ago, already 18 million addresses compiled): http://wiki.openstreetmap.org/wiki/WikiProject_France/WikiPr... ...or this meeting in London which took place yesterday(!) and was the kick-off of a similar effort in the UK with some funding from the cabinet office: http://lanyrd.com/2014/openaddresses/
