Whenever I see such comments, I can't help but laugh. Some people believe that the current level of technological development is the absolute peak, no one can do anything better without compromise. In a year or two there will be a new, lighter MBP chassis, of course it will overheat and have a very weak battery, the iPhone Air will be a failure due to the battery, Apple's own modems will work poorly, the Mac Mini in the new housing will heat up, and so on. This group of people thinks that the most valuable company in the world does not test anything and can no longer come up with anything new and good. Comical. Have a little more imagination guys.
It's not a tech/engineering problem, it's a patent problem.
