I use mine primarily as follows, in order of most use:
1. For audio and video Podcasts, using the default Podcasts app. When doing chores and not in a location where I'll bother anyone, the 520 is upside down in my breast pocket (speaker facing up), playing through the speaker.
2. As a streaming music player:
- Mix Radio,
-
Music and Audio,
- Xbox Music (soon to be using my $50 yearly subscription, which tubemonkey posted in Dec.)
- FM for local radio.
The app Music and Audio is one I've just begun using, and I don't yet understand if it's doing something illegal, since it allows song downloads. After the download, if you scroll to that song and press the floppy disk "save" icon, it's now able to be played by my other music app (XBox Music), implying it's totally freed up, which seems a lot like I've stolen it.
3. As a personal video player, playing TV that's been manually offloaded from my TiVo using
old tech.
4. As an occasional offline GPS nav system. But that's been mostly in theory, as I have other. bigger-screen GPS alternatives.
