Once you try android and figure out that your Samesung will develop a nasty lag in about six months and won't see marshmallow until android n is about to drop. You will be back . I have all the platforms in my family all on the latest software and I understand the frustrations with Microsoft , windows 10 is a game changer. One ux across desktops, laptops ,tablets, and mobile. Unless you are on a nexus device android is systemically broken . Ios is nice but I find it extremely boring and shares zero commonalities with OS x . BlackBerry 10 has had the rug pulled out by managment and is essentially DOA.
