David Chalmers, in his preface of Clark's Supersizing the Mind :
"A month ago, I bought an iPhone. The iPhone has already taken over some of the central functions of my brain. It has replaced part of my memory, storing phone numbers and addresses that I once would have taxed my brain with. It harbors my desires: I call up a memo with the names of my favorite dishes when I need to order at a local restaurant. I use it to calculate, when I need to figure out bills and tips. It is a tre- mendous resource in an argument, with Google ever present to help settle disputes. I make plans with it, using its calendar to help deter- mine what I can and can’t do in the coming months. I even daydream on the iPhone, idly calling up words and images when my concentra- tion slips.
Friends joke that I should get the iPhone implanted into my brain. But if Andy Clark is right, all this would do is speed up the processing and free up my hands. The iPhone is part of my mind already."
