I managed to get the libprs500 software suite working on the laptop today.

This is going to be a good thing. There’s a Linux command line utility, prs500, which enables you to remove files from the SD card and/or the Sony internal memory. There are some jpegs and mp3s in the internal memory, these came with the device. I saw, I listened, now I can delete. It appears that I can copy jpegs/mp3s onto the reader as well.

So onward and upward we go.

Update: prs500 is also available via the Mac CLI.  Begin-to-end documentation is a little light on all this; I’ll attempt to post what worked for me, in a more cohesive fashion.
