So today I completed a switch of my calendar and contact information from Palm Desktop to OS X's Address Book and iCal. After getting everything kosher in iSync, my Palm m505 is now syncing happily with Address Book and iCal. The only thing I'm still using Palm Desktop for is the Memo Pad feature for my various lists and notes. If anyone knows of a sync-able alternative, I'm all ears. Why the switch? Well, I just acquired a Newton 2100 (thanks again, Damien!), and there are methods for getting it to sync with that info. I also plan to get a Bluetooth-enabled mobile phone in June, when our current contract is up, and would like to be able to sync all of my info with that as well.
