I'm a little dismayed they continue to relegate iTunes remarks to music. It is the Media Hub for the entire Apple eco-system! Movies, Books, AudioBooks, TV shows, video... It is the gateway for the Apple TV to get to all of my stuff.
The most horrific thing to me about iTunes is it can't be trusted 100% to keep the library straight. Things can simply disappear and you have to show iTunes what happened to it. How the hell can something just disappear? It should rigorously protect the location of files and their integration into the database.
Another thing is the Dan Brown-esque intrigue to get the library transferred to another computer. It should be as easy as putting the whole folder on the new computer (PC or Mac - shouldn't give a ****) and saying to iTunes - here it is. Right now there are many files and even after following directions, everything - all my careful organization and meta data for my videos is gone. WTF.
It's not about making changes to interface or features that will make it better. Get the stuff under the hood rock solid and RELIABLE and that'll win the war. The dressing can come later. There has been WAY too much focus on the dressing.
