Insightful look at some of the implications of the new M7 chip in the iPhone 5s:
…the M7 can tell when a iPhone 5s user is in a moving vehicle. With this knowledge, the iPhone 5s will not try to join WiFi networks that come up around your car (which will save battery life). An even more helpful feature is that Maps will be able to automatically transition from driving directions to walking directions as you leave your car.
I’m most excited about the WiFi! It’s so annoying the way my iPhone joins WiFi networks when I’m on the bus going through town.
