I'm a big fan of OpenStreetMap in theory as well, but once Google launched vector maps with really solid offline caching for their Android app it made it a lot harder for me to consider switching. I know OSM will let you cache tiles for offline viewing, but the level of caching you can do with vector data is a whole different level.

OsmAnd nightly build (0.7.0 branch) is GPL'd, with offline vector OSM maps and it's mind-blowing. Navigation works, with voice. There is now a native rendering option on some devices, it's pretty spiffy. It can also record GPX tracks, with optional background service. The vector map of Croatia is 20 MB compressed, with a huge amount of POI data. Daily, an average of 50000 points are added to the map of Croatia. I've actually stopped using Google Maps, OSMAnd is the best map app and it's completely offline.

Wow, it's come a long way since I tried it. Thanks for the heads-up.
