That's bad for Pre users.
And of course Palm could have used the Apple provided iTunes XML file to make their own, documented and stable sync solution, but chose to simply have the Pre masquerade as an iPod instead. So it's not as if Apple is prohibiting anyone from syncing with iTunes or forcing Palm's hand-- Palm just decided it would be cooler if the Pre acted exactly like an iPod.
