I noticed it quite by random, but it really bugs me. Apple should know better, and they should be able to synchronize their teams better, even if I am sure that they consider working on windows quite a punishment. So here we go with a picture:
Why does Safari looks that horrible, while iTunes looks that nice? I like to know. It does show that nobody is untouchable and good UI is an eternal vigilance. A consistent look is really needed and this ain't it.
(oh btw, that is, from top to bottom, Vista, iTunes, and Safari)
