Apple has kicked Google Maps to the curb with the iPhone 5 and is going with a new mapping program, and it's not looking too good so far. The new Maps App has already been in the spotlight for bad reviews and serious criticism. On top of that, Apple has also done away with YouTube as an embedded app. Both Google Maps and YouTube will be available in the App Store, but they've been removed as embeds in an effort to get you deeper and deeper into the Apple ecosystem.
All iPhone apps have to survive Apple's vetting process. And while Apple is a closed system, Android and Google run an open platform, and it's one people find extremely appealing.
