The dash cams I've read about all have weaknesses, like
one article touting their favorite, which has the major weakness of not being able to move the video off the phone. Or
another where it costs $2 per month.
DailyRoads Voyager on Android is still the best.
Some built-in apps I use:
- OneNote (built-in or did I install it?) - syncs perfectly and immediately across platforms.
- Nokia Mix Radio - the free version seems comparable to the other free ones like Pandora.
- Podcasts - if you've used a Zune, it's the same interface. Bugs include forgetting (usually once per podcast) that it has played a podcast, and slow automatic removing of played podcasts. Due to the phone's 512 MB of RAM, subscribe to video podcasts at the lowest offered quality. Even then, long video podcasts of about an hour or more will experience stuttering towards the end.
