You know, iTunes serialises the library in both XML and binary formats. Instead of masquerading as an iPod, why doesn't Palm create their own syncing software that uses the XML library file? This is why the XML file exists in the first place.
Maybe a Pre user can say why it would be better to pretend to be an iPod. Surely it can't just be because they don't want to write their own software and instead decided to leech off of the iTunes/iPod integration.
