More Apple Maps in your third-party apps: There are some who would prefer that Apple's Maps stay far, far away from their third-party apps. But if you like Apple's implementation, you may see more of it in your other apps in the form of directions and "map snapshots."
Xcode 5: While not mentioned during the keynote, the next version of Apple's iOS and OS X app builder, Xcode 5, is around the corner. A developer preview is available today, with the full app presumably to be released later this year. You can read about Xcode's new features on Apple's website.
And many more...
This seems like a lot, and it is. But really, these are just the features I spotted during the keynote Monday and on Apple's website. iOS 7 is clearly a major release from the company, and I bet there's a whole bunch of interesting new stuff hidden away for us to discover when it actually ships in the fall.
