Marco "Tumblr, Instapaper" Arment tells Dan Benjamin:
One of the reasons many of us...love Apple products is because they think about a lot of the details that a lot of other manufacturers don't, in both hardware and software. And it's those little details that a lot of people think don't matter, or aren't worth the time and money to get right, that add up to a really great experience and goodwill from your users. So that's always been a high priority for me, to try and get all the details right.... Even if somebody has never run into something, I'm still happy it's there, because for the few people who do run into it, it makes them a little bit happier. If you look at a lot of the features of luxury cars, for instance, they're features that most people won't ever use. And they accidentally discover it sometime, they're just a little bit delighted by that.... And if we can do that same thing in software by providing these little delights to users, or by smoothing over a few rough edges that they should never have to see, that adds up to a significantly better product than one made by a firm that doesn't really care about those details.
I find less irritating tools to be less irritating.
