Something I've been wondering, and today's video seems to confirm is that there is no To Do synching? Or are the To Do's just synched as another calendar? This would be a real deal breaker for me. Most of my 'productivity system' is based on To Dos. Anybody has more information? Thanks.
If you're talking about iCal, I'd assume like the previous poster said, they will most likely stay associated with the calendars they were created for. As for the To Do addition in Mail in Leopard, I'm sure we'll see an update for that functionality, obviously when Leopard ships.
