One tap in the car allows me to turn on Bluetooth, turn on GPS, turn off WiFi, connect to my Bluetooth stereo system, launches my music player, turn on auto rotate and adjust my brightness settings. Another tap reverses all those settings. I use NFC everyday.
Ya, I've seen this function - NFC tags seem neat....
But why would I tap anything when I simply leave all that on all day because it doesn't compromise battery life. When I get in the car, my iPhone just connects. When I get home, my iPhone just connects. When I'm using maps, my iPhone just connects.
No tapping required.
