We don't have a choice in the first place, minding or not. People who would mind missing a 3.5mm jack or replaceable battery have no say anyway, as none of the flagship devices on the market have either.

Have you ever wondered why none of the flagship devices have one?

If the demand existed the devices would as well.

That only holds if you believe the market has a high level of efficiency.

Maybe if we wait long enough, the distribution of devices being manufactured will match consumer preferences, but I don't believe that to be the case today. The iPhone Mini sold ~millions of units. That may not be enough for Apple, but it's certainly enough to make a profit, yet nobody's building small phones now.

That statement looks like an assumption. Do you care to back it up with some factual sources?
