If the customers start sympathizing like that then they're going to stop listening to us and only act according to the other constraints you mentioned. If i go and buy a Pro Retina, the screen is the last thing i want trouble with, and if they fail in ensuring that it works, they should just replace it. Period. I don't give a damn about thresholds and whether im being 'reasonable' in whining or not. Maybe it's just me i want the best when i pay for it. Screw the shareholders and suppliers.
