I would like to point out that any individual's opinion is mostly likely just for him/herself. He/she might be more tech-savvy, or knows more than average consumers, but that does not translate to be more representative.

For example, I absolutely love thinner phones. I cannot revert to thicker ones after each time I switched to thinner ones. I guess my experience aligns with the majority of the consumers, but I do not know.

I totally respect Apple's (or any smart phone manufacture) decision, they certainly know much more than me on how to cater millions and billions consumers.
