"We love the computer because it heralds a new era of immateriality for technology that has remained stubbornly physical, despite our wishes to the contrary. The new MacBook is 13 millimeters thick—thinner than two pencils stacked on top of each other. The Microsoft Surface, a tablet with an attached keyboard that’s supposed to be taking on the hidebound laptop market, measures nine millimeters. The iPhone Six hovers around seven millimeters. The particular dimensions of these devices speak to two desires: We want our screens wide but as thin as they can possibly be. Technology is trending toward two dimensions."
