I'm still doing catchup on old Macbreaks...well two weeks old...

I caught your comment about Devonthink not having tags. I don't have a major use for one of those catch-all, suck-em-in-and-see tools, but I have some use for one. I got K.I.T (Keep it Together) and it has a comments field for each mp3, pdf, picture, word doc, whatever you throw in there. I use that for tagging. It has Smart Folders which will sort on the basis of those Tags which is all I need really.

K.I.T. is pretty cheap and available at http://reinventedsoftware.com/
