It's gone through quite a few minor revisions as of late, but Apple has today taken the wraps off a fairly big redesign of not just iTunes for OS X and Windows, but iOS devices as well. The latter will be making its debut with iOS 6 on the 19th, and you can expect a simpler interface in all incarnations -- "dramatically simpler," according to Apple's Eddie Cue -- with a carousel up top paired with a flattened grid of icons below. The desktop version also sports a new mini player, which now boasts search functionality while staying decidedly minimalistic, and a new "Up Next" feature lets you cue up songs and see what's coming at a glance. Those UI changes naturally extend to the store component as well, and Apple is also promising improved performance throughout. No firm release date for the desktop version just yet, but Apple says we can expect it sometime in "late October."
