Your astute observations are exceeded only by your fine writing.Every year I upgrade yet theres always people moaning on forums I've never had any issues.
I've seen the new ipad on display too and it looks fine so all these posts are questionable if they are really true.
The issues and variation between devices is a by product of their insistence on outsourcing much of the assembly work to slave labor countries. It generates profit but it comes at a cost. Personally I'd be fine paying a little more for the devices and have them made by more competent workers and people who weren't being taken advantage of.All of tech has this problem. But then again it's not a problem. It's a fact. Companies appear to have difficulty in manufacturing and assembly. Apple doesn't make the displays...they contract that out. The components are never all perfect and apple or any other company clearly doesn't have time to inspect the devices as closely as we do. It's not their 5-900 dollars after all. I'm going to be ultra picky with my dollars.
