After reading several raving reviews about Delicious Library, since I'm a DVDpedia user, I gave it a spin - my thoughts.

*** Pros ***
1. Gorgeous user interface
2. Can manage several types of medias from a single tool
3. The iSight idea is nice, but I don't own one so I don't know how well it works.
4. Good integration with the address book and iCal
5. Good integration with amazon.com
6. Can import from other cataloging applications

*** Cons ***
1. It does detects my DVDpedia library, but for some reason doesn't import anything, which makes the import feature kind of worthless in this case
2. There's no IMDB support and international user/media support is very bad (how hard/expensive can that be when everybody else is doing it? I mean 40$ isn't exactly pocket change)
3. The application itself feel sluggish, the contextual menus sometimes don't work or need a 2nd click somewhere else to pop up
4. No documentation or help file, only a link to a FAQ on a web site
5. If there's a way to manage the fields or control of what's being imported, I haven't found it.
6. No HTML export, you have to use a 3rd party hack to do it.

I think it's a good start and they are good ideas in there, but it needs more work, *far more work*.

Between the nasty bugs, the lack of International support, the lack of any form of documentation and the obvious features missing - important "obvious" features seen in most (if not all) other competitors products - I can't justify paying 40$ for it.

For me the bottom line is I'm mostly disappointed with Delicious Library. Clearly the application was designed for aesthetics and form first and function in the process took a 2nd seat.
