Remember The Milk update is out and it now has push notifications for task reminders! Yay! I know some people don't like that fact that although the app is free, you have to have a pro subscription to RTM @ $25/yr, but I love the service and think it's well worth the subscription price for how useful it is for me. I'm so much more productive since discovering RTM; I've tried other alternative services and apps: Toodledo, Pocket Informant, OmniFocus, Things, Reqall have all failed to give me the flexibility and/or the stability and seamless syncing that I get with RTM. Love it. Quite simply - Los Perros Cojones.
