Mac OS since a few versions and Apple Apps are such a strange combination of interface hiding and eye candy. And Windows isn’t any better.
My word for iTunes is c r a p because it totally confuses me. Mail isn’t much better. It seems to move mails into other mailboxes but it doesn’t. Why?
In former times buttons with gradients showed you what to click and shadows gave a nice extra kick. But what is vibrancy good for? It always makes me feel like my eyes have gotten much worse.
Design should be simple, but I need to be able to use the app. And not ask myself “what did I click to land here and how do I get back”.
