You'd like Apple to continue to make a 4" phone. I get it. Fact is, when the larger phones are introduced there will still be ample inventory of 4" iPhones and they will be updated for some time to come. Now if you're they type who has to have the latest and greatest, that's a first world problem with little sympathy from me. Heck, we're posting in a tech forum about an upcoming phone. All of this is a first world problem.
The crux of my issue with your quote is the insistence that larger phones are for the less tech savvy people. Forgive me, but that premise is stupid.
Not you, but the premise. What empirical data suggests that a person with a smaller phone is somehow more technically inclined? Forget empirical, I'd settle for anecdotal in this case. There is no correlation. It's like you're looking for an excuse as to why people like larger phones. There is no excuse or single reason. People like what they like for myriad reasons. MR is one of the more technically savvy forums and there are a crap ton of people here with larger phones and a boatload more wanting them. Are they less savvy than those who want the status quo? Sometimes I think we can resort to high drama to get our point across when it's not really necessary.
It's totally okay to express preference without denigrating the alternative.
