iPhone
The modern iPhone employs Ceramic Shield front cover and aerospace-grade aluminium construction. Apple claims this represents a four-fold improvement in drop performance over previous generations. The device can withstand drops from approximately two metres onto flat surfaces under controlled laboratory conditions.
However, the iPhone's operational lifespan typically extends to five to seven years before software support ceases and battery degradation renders the device impractical. The screen remains vulnerable to scratches from keys, sand, and the general hostility of pockets worldwide.
Mountain
Mountains demonstrate durability on a scale that renders human timekeeping somewhat irrelevant. The Himalayas have been rising for fifty million years and show no signs of product discontinuation. Erosion rates suggest a typical mountain loses approximately one metre per thousand years, a depreciation schedule no consumer product can match.
The mountain requires no protective case, no insurance policy, and has never been recalled due to manufacturing defects. Granite formations demonstrate compressive strength exceeding 200 megapascals, roughly equivalent to supporting fourteen thousand elephants per square metre, though why one would attempt this remains unclear.
