One thing where OSM really shines is the ability to downloaded maps for offline use. When i was travelling in South East Asia for two months i had an iPhone with an app that allowed me to download a part of any OSM map. Because every hotel had Wi-Fi access i just downloaded the parts where i was travelling and used that instead of finding a local SIM card. Even in pretty remote parts the maps were usually good, and in some cases they were even better than the Google Maps equivalent (e.g. Laos).
