iPhones will block texts while driving

"Users will be able to see Apple Maps, Apple's navigation application, while driving -- though they will be unable to input destinations. Other navigation apps, like Google Maps, will also work, although not quite as easily." (emphasis mine)

IMNSHO, the actual purpose is "we lock you even further into our walled garden." Wasn't there another company forcing their app on users of their OS? (Oh no, wait: Microsoft Baaad, Apple Goooood!)
