Guess I'm going to jump into this conversation after all. First let me say I am one of those people who do not care for integrated programs, while there are some that are capable of doing many things well, I find like others here have said that the functionality tends to become limited when you add too much to integrated products. I feel the same whether it is hardware or software. I prefer my phone to have phone features not internet, books, music etc.... the same for my kindle, mp3 player. With that in mind, I use the following software to manage my various databases.
music - Mediamonkey (
www.mediamonkey.com). Like Calibre this program is phenomenal because it allows its users to increase it's functionality with the use of user created scripts/skins.
movies - All My Movies (
www.bolide-soft.com). This is the only database that I use that has simplistic functionality, because I do not require the advance functionality with my dvds/blurays as I do with my music and books.
DTB books/audiobooks - All My Books (
www.bolide-soft.com) - I know there are many here who add empty books to their Calibre database in order to maintain these types of books, but I prefer to only have ebooks in Calibre because it is also the manager of my kindle content and if it cannot be added to the Kindle from Calibre then it does not go into Calibre.
All of these programs handle my databases well as they are separately, and each has some functionality that I would not require of the other formats, which is why I would not want to have them integrated into a single program.
