It makes some people feel superior, hating on Apple. They think they stand out and intelligent for not falling for the fad
Apple was good under Steve Jobs. It sucks now under Tim Cook. Tim tinker around the edges and don’t do anything revolutionary or exciting and the newer phones look ugly as well
Some "fad." Some time last month the one billionth iPhone was sold. That's not a fad, that's a movement. Over 800,000,000 are still in use!
