Core77 speaks with Jonathan Ive on the design of the iPhone 4: Material Matters - Core77:
"While [design schools today may have] sophisticated virtual design tools, the danger in relying on them too much is that we can end up isolated from the physical world," he says. "In our quest to quickly make three-dimensional objects, we can miss out on the experience of making something that helps give us our first understandings of form and material, of the way a material behaves--'I press too hard here, and it breaks here' and so on. Some of the digital rendering tools are impressive, but it's important that people still really try and figure out a way of gaining direct experience with the materials."
