iPhone
The iPhone maintains functional operation for approximately 4-5 years before software updates render older hardware effectively obsolete, battery capacity degrades below useful thresholds, and newer models create social pressure that marketing departments would describe as organic consumer demand.
Physical durability has improved considerably with Ceramic Shield glass achieving four times the drop resistance of earlier generations. Nevertheless, the device remains vulnerable to moisture, extreme temperatures, and the seemingly magnetic attraction between glass screens and hard surfaces that physicists have yet to adequately explain.
London
London has demonstrated operational continuity for approximately two thousand years, surviving the departure of Roman administration, plague outbreaks killing one quarter of the population, complete destruction by fire in 1666, and sustained aerial bombardment throughout the early 1940s. The city has outlasted multiple empires, economic systems, and architectural fashions.
Individual structures display variable durability, with the Tower of London maintaining structural integrity since 1066 whilst post-war concrete developments have required replacement within mere decades. Westminster Abbey has hosted coronations for nearly one thousand years, a warranty period no technology company would consider commercially viable.
