Stop yawning. This is news for a gadget late adopter like myself. My MP3 player is replacing a Panasonic walkman thingie. Cassette tapes. Not pretty.
In addition to music, there some great podcasts out there, and now that I have my new toy, I can really take advantage. Yeah, yeah, I know you don't need a mobile player for these, but sitting at my computer just listening to something feels weird, and I can't multitask when intelligible voices are involved (I listen to instrumental music while writing for the same reason).
So, all this may be ancient news to those who didn't carry around a 5-year-old bricklike Nokia phone until finally shamed into upgrading, but here are some writing-related podcasts worth checking out.
They also describe an interesting outlining method, one J.J. Abrams uses, in which action is jotted down in a circle, the face of a conceptual clock that represents an hour of screen time. 6 o'clock is 30 minutes in, 12 is one hour, etc. It apparently is an effective visual way of seeing how the story unspools. Something to try out.
