WiFi
WiFi reliability operates on what engineers technically term "the law of maximum inconvenience." The signal will function flawlessly during casual browsing but will catastrophically fail the moment you join an important video call or reach the final boss of any video game.
The technology is susceptible to an astonishing variety of disruptions: microwave ovens, baby monitors, neighbouring networks, concrete walls, fish tanks, and the mere act of hoping it will work. Router manufacturers have responded by adding more antennas, though research suggests these serve primarily aesthetic rather than functional purposes.
Despite these limitations, WiFi maintains an uptime of approximately 99.5% in developed nations, though this figure drops precipitously during thunderstorms, important deadlines, and family gatherings where someone's child is attempting to stream videos.
IKEA Furniture
IKEA furniture exists in a state of perpetual almost-stability. The MALM dresser will support your clothing admirably for years, provided it remains undisturbed. The LACK table will bear the weight of your coffee cup with quiet confidence, so long as you never attempt to relocate it.
The Swedish concept of "good enough furniture for everyone" has resulted in products engineered to survive precisely one and a half relocations. The particleboard core, when exposed to moisture, expands with a determination that defies geometry, while the cam locks, if tightened beyond finger-tight, will strip with the inevitability of seasonal change.
Yet millions continue to trust their possessions to these constructions. The PAX wardrobe system has protected interview suits and wedding dresses with remarkable dedication, asking only that you avoid breathing heavily in its direction during humid summers.
