"Apple has discontinued support for legacy Palm OS devices in Mac OS X Snow Leopard's iSync 3.1.0, according to sources familiar with the latest Gold Master build, requiring users of Palm OS devices to obtain third party support for syncing their Palm Desktop information with Mac OS X's Sync Services."
I'm not really surprised that Apple is cutting ties with the old Palm OS conduit. Palm themselves have also halted development of products based on Palm OS so it makes little sense for Apple to continue supporting the Palm OS conduit in their iSync product. Additionally, Mac OS X 10.6 Snow Leopard will be the first version of Mac OS X that will not include support for Apple's own PowerPC-based PowerMac and PowerBook models.
For Palm users who are also Mac users, I would suggest switching from Apple's iSync software to Mark/Space The Missing Sync for Palm OS. The Missing Sync will allow you to sync with Address Book, iCal, Entourage, iPhoto, and iTunes. You can learn more about the Missing Sync on the Mark/Space website.
