Apple

I tested it in my iPad and it’s an eyesore and genuinely less readable.

In a simple mechanical sense the glass effects are well done but they create ugly imperfections when covering different backgrounds. In my opinion Windows Aero was more tasteful.

There is also a degradation when it comes to buttons and control frameworks. In previous versions of iOS it was easier to determine what was a control layer and what was a content layer in the UI. Now the content layers are minimized or even hidden for a non appreciable “aesthetic gain” I think in a quest to further make the UI look less technical, in an user interface that already has been made less readable by previous aesthetic considerations (the removal of obvious buttons, which, from an IT standpoint, I run into issues with every day where a user cannot determine what is a control element vs what is a design element)

sixcolors posted a great breakdown on icon regression as well. A lot of icons look downright sloppy or almost like placeholders while penalizing previously well designed icons by third party devs that don’t conform by putting them in the community-coined “bubble jail”.

In short, there is a distinct lack of taste and a poor execution of ideas that is also hostile to third parties who produce software that looks better than this new paradigm.
