The way I see some people coming here complaining about what the iPhone has that they don't like and/or what the iPhone doesn't have and they want is tantamount to going to McDonalds every day in hopes of getting a Whopper... Makes me smh in utter disbelief.
Guess there's a few kinds of people. Some of us make suggestions and give feedback. I often email companies or use feedback forms. I'm generally positive and back up my suggestions. Then there are those that take whatever they're given and do not care to think anymore about it. Both types are ok. Probably every product I own I see where improvements can, and oftentimes are, made. It's called innovation and progress. I take part in that process. Apple offers a place to offer suggestions as well, which I have utilized.
I agree that these forums are not the place for that kind of discussion simply because many "enthusiasts" are linked emotionally to the product they bought. In my opinion there's always room for improvement, changes and innovation. Heck, even the Whooper has changed over the years.
I will always be one to see how things can be improved. Even so far as to make things myself. Engineering is fun, improving is fun. I made great additions to my camp stove for example.
Never say never. Apple has said it will not include many features and it lacked features that were eventually added. We may have the option to hide apps, may have an LED. Look at the history of the product here.
