Attention to detail, like most facets of truly good design, can’t be (and never is) added later. It’s an entire development philosophy, methodology, and culture.marco arment is the man behind instapaper, an application i use more than almost anything else on my iphone and ipad. instapaper's sole inexplicable design feature is the trashcan icon in the ipad interface. when pressed, it shows only an archive button which sends the article to the archive; no other action is possible.
a) trash ≠ archive, b) why have a 2-step button push when just one would do?
update, march 2011: after talking this over with hammer, who thinks there is a subtle, behavior-changing motivation behind the decision, i remain unconvinced.
