"You might argue that an iPhone without connectivity is, well, an iPod, but its not. To state the (obviously overlooked) obvious - it is a phone without connectivity and that over time the ease and evolving practice of disconnecting fundamentally changes our assumptions of what we can expect from a phone, which in turn alters our expectations about the connectivity of other people." Jan Chipchase on pause buttons and understandings of what "social" means. Excellent.
