I think iOS 6 was the best iOS.
Looking at the original review, Pages looks old. Everything is going flat and Apple did the right thing going flat. The problem is that iOS 7 went more and more complicated and bloated with crazy color gradients.
A). There's a difference between 'flat' and 'stripped of all context'.
B). My mother always told me that just because everybody else was doing it didn't mean I needed to.
I have no real problem with flat per se. But Apple seemed to be trying to force change where it wasn't needed. People were used to specific aspects of an interface, buttons that actually looked like you should click them, arrows actually meant 'back', etc. Changing the look a bit is ok but the action still needs to be intuitive.
My biggest gripes with the iOS changes is the use of thin stick figures, the fact that the same actions are not consistent throughout Apple's stock apps (ie, the trash can is on top on the right one place, on the bottom left in another, etc.), and all that WHITE.
And don't get me started on white background, very light grey bars with white text. Everything just blends together. No contrast. Might loo good to some but very hard to use on a day-to-day basis for any length of time. Look at the new autocorrect......
I designed software for close to 25 years. Apple broke almost every rule of good interface design. And not for good reasons. As far as I can see it was 'just because we can'. I mean, exactly what was accomplished by using dots vs thin bars for signal strength? And WHITE everywhere? Any good software designer kows that brilliant white is harder on the eyes.
Even Apple had to backtrack by putting in options like the bold text, button shadows, and reduced white point.
But what's done is done. I suspect over the next couple of years we'll see them slowly fix the most egregious missteps. They have already been trying with the options I mentioned.
End rant. Sorry
