"At a glance can the average user tell the difference between iOS 2 or 3 and 6?" (A) Probably can't tell because iOS 6 is on all the phones, zing! (B) If he's trying to cut and paste he can tell. iOS 2 won't let him do it, iOS 3+ will force him to copy the entire body text randomly, iOS 5+ will randomly offer a handful of options that generally do not include the one the user is looking for. (C) Ok, so it's visually stagnant. I guess I'll agree here. Turns out, there's usually less to disagreements than first glance might indicate. "any fundamental work on improving the user interaction and look & feel of the thing in 5 years." There are certainly new gestures and there's voice. There's new functionality in the buttons and from the lock screen. I would not say this is totally accurate. "I find it unbelievable that there's nothing that could be done better and that iOS was launched with perfect interaction design, fully formed from the heads of the designers, or perfect visual design, reverently propagated to the modern day and on into the future." I don't see anyone claiming it's perfect but there's a good argument to be made that Good Enough + Consistent > Better. Which is to say that Apple users, who do get updated to the latest patch, might be jarred if Apple constantly yanked the UI here and there for the sake of slight benefits or "keeping the look fresh".
