Finally, Reminders now syncs with iCloud. And it's a full two-way sync, meaning you can add tasks while signed into iCloud and they'll appear on your iPhone -- and vice-versa. That's a great perk for cross-platform task management, among other things.
If you use Facebook and/or Twitter as part of your marketing efforts (and you should), you'll greatly appreciate the option to push out updates using nothing but your voice.
That's not only a time-saver, but also a potential life-saver for anyone who thinks it's okay to tap out a status update from behind the wheel of a car.
