It is true that there's no way (so far) to pull the book out of an LRX (the DRMed variant of Sony's format) but there is a way to pull it out of LRF (the non-DRMed variant). That app is pretty rough, though, and the results are mixed. If you want something out of an LRF it's easier and more effective to open it in the PC side software and copy the contents out -- preserves the formatting for the most part.
