Honestly I think it&#x27;s good old fashioned Developer laziness, and&#x2F;or marketing. They&#x27;ve whittled down all their Windows offerings to just iTunes for Windows, which handles devices, music, streaming, movies, etc. etc. and they don&#x27;t want to have to develop and maintain multiple applications.<p>And why OS X is infected? They probably share a fair amount of code.<p>It&#x27;s just feature creep. On iOS you have a Music app, a Podcasts app (which is garbage), a Store app and I believe Movies and whatnot are under videos. It makes a certain degree of sense, yet in OS X universe, all of these are brought down into a single app with just a clusterfuck of a UI.<p>I honestly feel a little bad for whoever has to design it, I can&#x27;t imagine how difficult it would be to combine all that functionality and feature creep into a UI that felt even a LITTLE coherent, and honestly they do a pretty good job, it&#x27;s the problem they&#x27;re handed that should be addressed, i.e. break it up into a few apps.
