I'm thinking of picking up a Galaxy S3. As an iPhone, iPad and MBP user, I'm confused as to the best way to replace my iPhone with an android and still sync my contacts, music and calendar with all devices. Do I just sync everything with google? Will there be any loss of functionality that I may not expect? (going over to android) I know the 5 is coming out and I will probably wait to see, but I'm expecting to want to switch.
