I'm reading a very interesting book by Virginia Postrel called The Substance of Style. Her central thesis is that we have entered the "Age of Aesthetics" and "look and feel" (along with design) is assuming ever-greater importance. Ms. Postrel managed to neatly deflect criticisms that aesthetic pleasure is 'superficial' or argues that it is rather the case that it taps deep into human instincts. This certainly seems a persuasive argument to me. I'm about a third of the way through and enjoying it enormously, very thought provoking. I might try to write a proper review when I finish it.
