Macrumors #neversatifiedever
Complains for years that Apple needs a larger screen. Apple makes larger screens. Macrumor complains about too many choices.
Screen size is not the issue here. People are happy about having those choices. What they don't like is that the bigger iPhones are also getting the better features. i.e. Apple is forcing you to buy a huge (and more expensive) iPhone if you want the best stuff. And not everybody wants such a huge phone.
The difference between all the iPhones that come out at the same time should only be the screen and battery size.
So when you go and buy a new iPhone, your only concern should be to pick the right screen size for you. And not having to think about what you're giving up if you're going for a the smaller iPhone.
