[unboggling]

And thanks for the discussion of Boot Camp, Parallels, and VMware. I ran Windows from a partition for awhile years ago when I needed it, generally worked fine except for hassle of rebooting to switch. I've not needed any MS OS since then until perhaps now. I didn't know about Parallels, I'll look into it. Penguinaka has a great script for preprocessing books before adding to calibre, and others have other tools that only run in MS environments. Parallels might allow me to use them (I think) with little muss or fuss. I'll look at VMware Fusion too.
