The hidden gem in today's WWDC keynote

Today's keynote at Apple's WWDC in San Francisco brought plenty of cool tweaks to both the desktop and iOS devices. Rather than go through the extensive list of impressive features (which will be available on Apple's website shortly, I wanted to focus on one (relatively) hidden gem: Reminders. At first glance, Reminders is nothing more than a to-do list. However, it happens to be a location aware to-do list, meaning it can remind you of specific tasks when you arrive/leave a certain place, or happen to be in the vicinity of another place.
Imagine the possibilities if the APIs that make this work are also available to developers: You could set your phone to automatically text someone you're headed home at the end of the day, maybe even fire off emails when you're somewhere you don't want to be bothered, etc. It could almost be a location-based, mobile version of Automator.
Sure the other features will get more press, and will be more key in the ongoing market share battle with Android, but for me, this is the feature that makes it most feel like we're living in the future.
