Favorite iOS 5 minor feature

Yes, iMessage, iCloud, WIFI syncing, and the notification center are awesome, but I was curious what is everyone's favorite minor feature that iOS 5 added.

Mine would have to be:


  1. The ability to have spell check on while having auto-correct off
  2. Multiple routes in maps
  3. Weekly calendar in landscape
  4. The ability the use my iPhone while syncing
