Bermuda Triangle
iPhone
Apple's engineering has produced a device of remarkable consistency. Modern iPhones achieve uptime percentages exceeding 99.7%, with most failures attributable to user damage rather than component malfunction. The software ecosystem, while occasionally frustrating, maintains predictable behaviour across billions of installations.
This reliability has become so normalised that users experience genuine psychological distress during the rare moments of malfunction. The iPhone's dependability, ironically, has made its failures feel more catastrophic.
