Thanks to Kovid Goyal, the Sony Reader’s very own terrible software (iTunes wannabe) can very soon be decommissioned from my software collection. The libprs500 project, multi-platform solution written in Python works very well and allows to move data between Sony and your Mac / Linux / Windows. The UI is actually pretty decent, considering that it is not native Cocoa app:
You can also edit metadata, which is very important because of the limited screen space on PRS500. As added benefit, the application gives you a reader for LRF file format that allows reading unprotected LRF books on the Mac/Linux as well in addition to Windows. Here is a snapshot:
And best for the end: the libprs500 can do format conversion from TXT, HTML, RTF and LIT (haleluja !) as well as PDF – as long as it does not contain too many images. Seems like Christmas arrived twice this winter – and we have still Macworld ahead 
Huge thanks to Kovid who wrote this thing and to Peter who made aware of it …
So. How will I be able to get this software??
