I'm actually super impressed with the recent progress that the Android OpenStreetMap client has made. In the past six months or so it's gone from virtually useless to being a full Google Maps replacement (at least for my use cases).

I found the actual map quality quite lacking, unfortunately. Your mileage may vary by location, of course. I had been testing using OSM for a project to get some data, and MapQuest both had the OSM data and their own proprietary data. I compared the two and it was really painful to try and work with OSM's data.
