One useful change Apple made in its new Maps app for iOS 6 is that a list of your most recent searches appears when you tap the search box. Even better, no matter where you are or what your last search was, the first option presented at the top of that list is always “Current Location to Home.” As long as you’ve selected your contact card under Settings > Mail, Contacts, Calendars and it contains an address labeled Home, this is a convenient two-tap way to get there.
