It still makes no sense to me why, on the Mac, everything is glommed into a single app. For years I've been hoping that Apple breaks it apart into separate music, video, app store, and device syncing/management apps. Why should I be locked out of playing music or a video just because I'm restoring my iPod, and iTunes decides that it wants to present a modal progress bar until it's done?
