I used to think the same. However is not true. I've had every iteration of iPhone from 2 to 5s, every iPad from 1 to air, as well as Mac air, mini and imac. I'm a power user.. I few hundred paid apps, I used to rely on jailbreaking my iPhone to get the tweaks I want, then I'd wait hoping that a new ios release would bring the tweaks to native ios. As apple started making it harder to jb I started looking at alternatives. My main worry was that I was so heavily invested in the ecosystem that it'd be hard to switch.
I bought the Samsung S5.... and it's as easy to manage in the Apple ecosystem as the iPhone. You can't use safari, but chrome is available on all devices. The big relief is I haven't needed to jailbreak or root because every tweak I want is available. There's a new os coming out, Android lollipop... But I don't really care, because I can do everything I want now as well as things I didn't even know I wanted... Like control my home theatre with the infrared blaster and have a file system of documents.
Now I've seen how easy it is to go out of the Apple system I'm now looking at getting Samsung tablets, the 8.4 S is far superior to the iPad mini 3. I'm also changing phones... But sticking to Samsung, I've had the iPhone 6 plus for 2 weeks and it doesn't get close in functionality to the Note 4.
I've seen alot of friends make a similar switch, I was definitely an apple fanboy so it was hard, but I slowly grew disillusioned with Apple..... Until they came out with the imac 5k which restored my faith.
