How are you Mac folks doing reminders and structuring to-dos?

As of Leopard, I’m a transplant from Entourage to the Mail/Address Book/iCal/.mac combo. Over in Entourage for the past 7 years, I created a slick Zero Inbox system by using delayed reminders, using a cool combo of Applescripts that removed emails out of the Inbox until a time when I needed to deal with them. I haven’t figured out a system yet in the Mail world.

I’d love to hear how you Mac GTD’ers are using timers/reminders to postpone to-dos until the time you need to deal with them. I’m intrigued by OmniFocus, but it doesn’t seem to be set up to do timers; more, it looks like a way to order ones to-dos in the sequence they need to be done. It might work, to switch from a popup timer world, to just remembering to look at a list. But before I dive in to OmniFocus, I’d love to hear how others are dealing with their to-dos using the Mail/Address Book/iCal/.mac combo.

Thanks for any ideas.
