I do apologize that my comment about dream-land (it was condescending.) But you are arguing impossibilities with manufacturing products with “precision engineering.” Apple is already doing precision engineering with top-end materials... (*they charge a premium because they’re products are almost always superior in build quality to any other manufacturer, and people are willing to pay for their products as compared to any other manufacturer as has Apple delivered incredible products with few problems more than any tech company. How many products have been recalled or had serious issues in regards to Apple compared to Samsung, LG, Sony, Dell, HP, etc etc... ( as a customer service and geek squad agent dealing with all electronics... Apple would have a return rate far lower than the other companies, I had more open box HP, Samsung, Dell, LG, Sony, Razer, and other companies more than Apple. People returned Apple products with “buyer’s remorse” almost 99% of the time. I had to ship 1 iMac back to Apple in my 3+ years of geek squad and CS at Best Buy.
Let’s go off your unrealistic view, if Apple somehow made an even more strict engineering practice with iPads, Macs, iPhones, iPods... and even used Titanium, Steel, Magnesium Ion, or 7000 series aluminum and diamond displays or whatever, physics WILL STILL affect them and warp the materials. No electronic is perfectly symmetrical or without flaws. I hate using this word, but it is impossible for any physical object to not have deformities, imperfections, or issues.
This is all learned from physics classes, studying, common sense, college, 18 years of using just about every kind of device or product consumers can buy. I have never had a product without even a tiny tiny problem (to think even more strict precision engineering can produce an iPad that is 99.99999999999% perfect is false.)
Kallum.
