Like the Apple Time Capsule power supplies that seem to be dying after 18 months due to a design flaw?
(Or the problems Apple had in the past with incorrectly applied thermal paste, plastic blockers being left in fan vents, cracked cases, discoloured cases, ridiculsouly easy-to-scratch portable devices, battery recalls... That's just off the top of my head and not considering design flaws which were made on purpose, like non-removable batteries.)
I'm not saying Apple's hardware quality is worse than other companies -- they've all had issues over the years with their designs or choice of suppliers -- but the idea that Apple have higher hardware standards seems silly to me. Somehow whenever Apple make a mistake it's dismissed as a one-off and forgotten about. It's a form of confirmation bias.
