Do you know how iPad will Sync without Push? Like will it just Sync based on the interval set? Like every 15 min? That would be okay with me for a while so that I can publish my calendar and get off of other calendars.For me, what will have me decline the invitation is no push notifications on the iPad. That is my main device for my calendar now, and I rely on push so much that I don't even think of it when doing my work. The support page says that it is only for iOS 4.0.
Also, I'm one of the few(?) that is still using Leopard and not SL and the min reqs are SL. Someday I'll get around to updating...
