Agreed. What you have said here is constructive, so thankyou for jumping in to help clarify the distinction here. While I could tell that this is all that the original poster of this thread had meant, I think it was just the ambiguous use of the word "essential" that led him to be misconstrued as meaning "essential [to everyone]", whereas he like myself would have only meant that as "essential [to those of us who either have needs for greater than is currently available to us]." (...or as you better put it: "ideal", as this is definitely much less ambiguous).
So now that between us we have hopefully cleared up any misunderstanding, hopefully this should help avoid any future misinterpretation, and people can now feel free to join in this discussion without fear, as it is an interesting topic, and can be helpful in regards to the progress of our much beloved technology to let our desires (and the differences between how we each individually use them) to be known by those who design them.
There was no misunderstanding the OP's intentions or use of the term "essential". No one is prohibited from joining in any discussions here at iMore, but that also means that no one is free from being debated or corrected when posting a statement that is factually incorrect. Too many people, as of late, tend to want to demonize the people who bring a false statement to light and make excuses for the person who posted it. Those who bring attention to lies are not the bad guys and those who stand by and let the lie stand or ignore it are not helping the person who posted the lie.
