"Apple has filed a patent application for improving the physical characteristics of stainless steel with nitride coating, which may mean the company plans to release scratch and impact-resistant devices in the future. \nDubbed Nitriding Stainless Steel for Consumer Electronic Products, the patent describes \"a cost effective system, method and apparatus adapted to provide a nitride layer on stainless steel used for the manufacture of consumer electronic products.\"\nThe process should create a \"durable, hard surface that is both scratch and impact resistant,\" while allowing the natural texture and color of the steel to remain visible. If this patent ever gets used in real life, expect MacBooks (and possibly other devices) that look just like the current models, but they'll be a lot more durable. \nThe patent application is available here. \n\n\n\n"^^<http://www.w3.org/2001/XMLSchema#string>
