iPhone
The iPhone presents a curious paradox in the realm of durability. Constructed from aerospace-grade aluminium and Ceramic Shield glass, each unit undergoes rigorous testing procedures designed to simulate the countless drops, splashes, and pocket compressions of daily existence. Yet despite these efforts, the average iPhone lifespan remains approximately four to five years before the combination of software obsolescence, battery degradation, and the irresistible allure of newer models renders it functionally obsolete.
The device's relationship with water remains particularly fraught. While modern iterations boast IP68 ratings suggesting submersion tolerance, the mere suggestion of moisture contact voids warranty considerations and sends users into states of acute anxiety. Rice, improbably, became a folk remedy for a device worth hundreds of pounds.
Waterfall
The waterfall operates on timescales that render human concepts of durability almost meaningless. Niagara Falls has been continuously cascading for approximately 12,000 years, having begun its descent at the conclusion of the last ice age. Victoria Falls has maintained its thunderous roar for over two million years, predating the emergence of Homo sapiens as a species.
Waterfalls do not require software updates, battery replacements, or screen protectors. They do not become obsolete with the announcement of a newer waterfall. The erosion that gradually reshapes them occurs over geological epochs rather than quarterly fiscal reports. Their durability is measured not in warranty periods but in the slow, inexorable movement of tectonic plates and the patient weathering of bedrock.
