From an article from the New York Times:

The New Yorker, a magazine that has always been heavy on text, took a different tack from its peers. Instead of loading its iPad app with interactive features, the magazine focused on presenting its articles in a clean, readable format.

“That was really important to us: to create an app all about reading,” said Pamela Maffei McCarthy, the magazine’s deputy editor. “There are some bells and whistles, but we’re very careful about that. We think about whether or not they add any value. And if they don’t, out the window they go.”
