We keep our converted books in a Calibre Catalog. I love
it for that. It has many--many--great uses. But Kovid does not claim, and never has, that it's a production tool. I, too, am a bit OCD in that regard--the right tool for the job, and all that. But people will always seek what they see as a silver bullet, the "easy way out," like magic diet pills, rather than spending a few hours learning to make a MOBI file. Hell, you can even make a passable MOBI now with WORD, for the love of heaven. Not what I'd put up as my work, mind you; but nothing wrong with it for DIY'ers.
It's not Calibre I object to, not at all
. It's the Whovian "Resistance is Futile" when you try to tell people something that they don't want to hear that gets up my nose. ;-)
