Hugh Pickens writes "iTunes has been criticized in the past for being slow and growing increasingly unwieldy as more and more media types have been added to what used to be simply a music player. Apple announced iTunes 11, the latest version of the program, at its iPhone 5 event in September and said the update would be released by the end of October, but Apple's deadline for the upgrade has slipped. 'The new iTunes is taking longer than expected and we wanted to take a little extra time to get it right,' Apple told technology site AllThingsD. 'We look forward to releasing this new version of iTunes with its dramatically simpler and cleaner interface and seamless integration with iCloud before the end of November.' The update is said to be the most significant upgrade to iTunes in the 11-year life of the program, which has grown from a simple music player to the most powerful retailer in the music business — and a force in the movie, television and e-books businesses — and, on Apple's PCs, the portal to its app store."
