You can add another name to the list of companies dropping Google Maps in favor of OpenStreetMap. When Wikipedia announced its new app for iOS today, they also announced that they would be using OpenStreetMap exclusively for the nearby view in both their iOS and Android mobile apps. Wikipedia feels this change will be a better fit for their goal of making knowledge available in a free and open manner to everyone.
This also means we no longer have to use proprietary Google APIs in our code, which helps it run on the millions of cheap Android handsets that are purely open source and do not have the proprietary Google applications.
