A woman told one of us that she had to use Apple’s assistive tool to make Apple’s undersize fonts large and contrasty enough to be readable.
So a person with a visual impairment used accessibility options to correct for it? This is a problem how? Later they confuse font weight with font size. Both are adjustable in iOS, of course if you really need very large fonts you will run into some sizing issues in some apps.
Huh? Nowhere in the article did it say the woman had a vision impairment. You went right to some "brain tumor" derogatory remarks.
This is why those interfaces work. Let's take a scrolling view for example. The traditional approach is to put a scrollbar in, and that's what most everyone was doing before the iPhone came along. The scrollbar is discoverable and it provides visual feedback. Sounds good right? Well it turns out using a scrollbar on a mobile device is a miserable experience. Swipe to scroll turned out to be the vastly superior method, and as soon as you learn to swipe (my 1 year old figured it out watching me) it is trivially easy to operate without any additional visual clutter.
I don't think the authors have a problem with swipe-to-scroll. The problem is that the lack of a scroll bar hides the scroll-enabled nature of a view. Apple also did the same shenanigans with scroll bars on Mac OS X. My father has huge problems with the new scroll bars introduced in OS X Lion. When scroll bars are set to invisible, he simply had no idea that something was scrollable. Sure, he can roll the scroll wheel to activate visual scroll bars, but if he doesn't know he can do that, he is stuck at square one (and he never really internalized how the scroll wheel works). Even when you make scroll bars always-on, the scroll bars are much narrower now than they used to be, so it's hard for a person like my dad to find and click on the small real estate.
Let's face it, Apple's "low discoverable" UI may look pretty, but it's not very approachable or usable by non-power users.
