There are excellent reasons to not choose iPhone, but this one warrants a click on the back button.
Other than the iPhone 6 upgrade (the smaller one has a screen size of 4.7", the same as the phone the author ended up picking), they've been getting smaller, lighter, and thinner every release. (At the expense of using the space to increase battery life, which is what I'd really like to see improved.) There has been zero increase in cost since the first release. Complexity could be an open question, but after using iOS and Android, I've found iOS slightly more intuitive than Android, which is still too rough.
Lack of customization and control are good reasons, but the first bit is bafflingly misinformed.
