I'm considering swapping back to iOS and the iPhone and looking for input as to how well it works these days with Google's services such as Gmail and Calendar. Brief background: Long time Apple user, including every suite of internet services they've released since iTools. iCloud was the final straw and I fully shifted to Google. (I don't care for this to become a debate on whether or not iCloud is any good, better now, better in comparison, etc., simply trying to clarify up front that using it is not an option I'm willing to consider.) For a time I was happy using them on the iPhone, but I figured it might be worth it to jump to a Nexus and go full Google/Android. I'm pleased with Android and like my Nexus 5, but when it comes down to the little differences between how the phone operates, how Google Now interacts vs. Siri, what accessories are available, etc., I find myself missing my iPhones past and drawn to the new 6s or 6s Plus. But I'm wondering how locked down iOS is these days to iCloud. Will it play nice with Google? Will I be forced to use Apple's Maps when Siri gives me directions? Will I suffer pop ups more often than my MacBook Pro's requests to enter or create an iCloud account? I realize some of this will be speculation with potential changes around the above from iOS 8 to 9, but I welcome your thoughts from those of you who also avoid iCloud but love your iPhone. Thank you for your input.
