When someone starts writing it's not unusual for them to want to creative, to be un-boring, so when they have a character talk, that character "intimates", "whispers", "suggests", "exclaims" and otherwise enjoys every imaginable bit of literary variance the author can throw at them.
More seasoned writers tend to just stick with "said". When a character talks, it's "said", "said", "said". Over an over again. Page after page. Turtleneck after jeans. "Said", "said", "said". It's used so often it just disappears, the mechanics disappear, the author disappears, and all that's left is the character.
Apple's iOS has a pretty consistent user interface. It's not perfect by any stretch, but it's more consistent than its competitors. Occasional page curl in Maps aside, the basic ways you move around the iPhone are the same, Apple app after Apple app. (And anything that's not tends to get hidden away so power users can "discover it" and mainstream users can live their lives never having to be bothers by its existence).
