I've used Calibre off and on for a long time; always abandoning it in search of something more sexy but always returning because sexy just isn't enough.
The thing that makes me search for something new is usually the slow metadata downloads. This time, however, in the interest of helping out, i"m here to say we need a 'Metadata download FAQ' (apologies if it already exists, it needs to be made much more obvious for idiots like me then).
I've purchased ISBNDB access. Shouldn't this make things much faster? Can other 'purchases' or such make MdD faster? For example, were I to log into Amazon somehow, would the metadata searches then returns results faster?
This doesn't even begin to talk about merging metadata results which would be my next 'abandonment issue'.
