Not my favorite format–but better than Sony’s own proprietary alternative. Details from BusinessWeek Online. I’ve mentioned the machine before, but in fairness to Sony I did want to highlight the PDF possibility. What Sony does have going for it: Many people will buy first and ask questions later. Meanwhile a BW excerpt:

Users will be able to load any .pdf file onto the reader, according to a person familiar with the device, as well as files with a special Sony e-book format. That means you’ll be able to read everything from magazine articles to analyst reports to out-of-copyright books.

Problem is that PDF itself is a proprietary format that Adobe can change whenever it wants. And in commercial books it tends to come with obnoxious DRM. Furthermore, regardless of conjecture to the contrary, you can bet that Sony will try to steer people to its format even if it in fact does offer PDF.
