Sam, we considered the Push approach, but we didn't feel that notifications would be reliable enough for the folks on iPod touches if they weren't near an open WiFi point.
I'm sorry for any confusion about the way the notification feature works - I'll talk to some folks here and see if we can make the "in the next two weeks" aspect clearer.
We are taking another look at this area of the application, but most folks seem happy with how the feature currently works. Since I can't promise you we'll change the feature to work the way you want, I wanted to be sure you know that you can get a refund on both versions of OmniFocus if you want one.
If that's the case, email
sales@omnigroup.com a link to this thread and we can get that taken care of for you. Again, sorry for any confusion.
