Here's some examples: * Telnav Scout: a typical GPS/navigation app. I guess figure using OpenStreetMaps is better than their proprietary data, and they don't want to be competing with Google and depending on Google for data at the same time. * Humanitarian Organizations (HOT): it turns out that you can get volunteers to trace maps from satellite imagery for remote places that have no other maps. * Backcountry/mountaineering: a lot of places in the mountains are poorly mapped in Google Maps. OSM is a lot easier to edit, and supports a lot more features when it comes to describing terrain and whatnot.
