I love the new features of iTunes 10. I love Ping, the new music-centric social network that Apple introduced with the new software. I just have one question: What’s up with the buttons?
If there’s one thing that’s Apple’s speciality it’s attention to detail in design leading to excellent consistent user experiences. So, then it remains to be seen why Apple would deliberately make the the close/minimize/maximize buttons on iTunes 10 different than on every other piece of software for the Macintosh:

It’s not as if it’s difficult to figure out how to use the new buttons, but they are the wrong size and in the wrong position. The buttons now make me stop and think about where I’m clicking. Why introduce this nuisance? It’s very unlike Apple.
