I don't get why people think they have to insult other people's taste on this board. I don't like the looks of iOS7 but I would never insult somebody else for liking it.
As the saying goes "you can't please all the people all the time". We'll have to leave it to history to see if this a lasting design, but the cleaner look adopted by Apple is kinda trendy now so those who don't like it may just have to grin and bear it for now
