We're providing notifications now in the best way possible to us. I certainly agree that calendar notifications which go through a separate server aren't ideal: what would be ideal would be for Apple to add date-based notifications on the device itself which had all the same options as push notifications (so we could specify different alert sounds and update the app icon, just like push notifications do). We've been requesting that feature for over a year (starting the day Apple announced push notifications), but Apple already had a lot on their plate for 3.0. (Hopefully they'll get to it for 4.0!)

We're not refusing to implement push notifications, but push notifications aren't possible for OmniFocus at the moment because your data lives on your devices, not on servers hosted by us. (We don't have any OmniFocus servers!) That means there's nowhere for us to push notifications from, unlike a hosted service like Remember the Milk.

(We could certainly enter the hosted service business, but that's talking about a whole different business model—one which would presumably involve some sort of recurring subscription fees.)

The calendar-based notifications which we implemented in OmniFocus 1.5.1 for iPhone aren't perfect, but they work pretty well. (They'll work even better when OmniFocus for Mac also updates the calendar.)
