Usability is not everything
Is usability linked to functionality? The less functional an object, the worse its usability?
Like earrings. They are the absolute worst. I don’t know how other people put them in, but it’s damn near impossible to do by yourself.
Pushing a slippery piece of metal through a tiny hole in your ear. And attaching the back, all by touch. Sweaty fingers and minuscule parts don’t make a good combination.
Of course clip-on earrings exist. Someone tried to improve the usability. But in doing so, they destroyed the whole concept of the earring. Clip-on earrings are like clip-on ties. They may look like the real thing, but they’re not.
Maybe some products aren’t meant to have good usability.
