Hmm. Looks like they've just removed half the interface. Does this mean you can no longer drag and drop because I trust iTunes to manage my media as much as I'd trust a cabbage to manage my finances.
iTunes has traditionally taken all the lessons and experience built up over the past twenty years about how to build an intuitive user interface, then implemented the exact opposite. It gets so many basics of interface design wrong I can't help thinking it must be done intentionally, just for a laugh.
Screen resolutions are very high these days - let's hide features, scatter them inexplicably around the screen and make people roll over to find them. Everybody LOVES blindly scanning round an interface to find what they're after!
Speaking of which, where shall we put the Add Playlist button - in the playlist section?
Of course not, just stick it on the bottom of the interface with the most vague icon we can think of.
Should we use our graphic interface for all our navigation?
Nah, let's put some buttons into the pseudo digital information screen for the hell of it. Because everyone will expect navigation to appear in the information screen won't they?
Shall we exclusively use dialogue boxes to announce critical features such as, "iTunes is about to delete everything off your iPod"?
Great idea! Everybody reads those. It's not like people just click the button they think is most likely to get rid of them.
