I've has iPhones since I started getting smart phones, and don't think I'd go to any other brand unless something major happened. Currently have my new baby, 7plus, and I am in love. Whenever I have to do something on my husband's Androids over the years, it's just so slow to respond to touch, it's not as accurate, it feels cheap in my hand, the camera has a hard time focusing and even then everything's a little soft. Not to mention a few times he has had to suddenly replace his phone, and in the meantime used my older iPhones... because even an iPhone 4s lasted longer (my 5s is still in great condition, and will be used as a backup/iPod).
I don't care about the "name brand", I care that it's a great product that just works so well for me. I don't need something where I can change the font on Facebook. I don't need something that will hold my entire music library on the device.
