I love playing with Calibre as well!
At home, no one shares my enthusiasm. They either don't read
or aren't into e-reading. It's nice to find a kindred spirit here!
Too bad I can't play with Calibre as much as I'd like due to recent surgery (working on a computer or laptop is not the best posture at the moment). But piece by piece my Calibre library is getting filled!
I hope your 360 arrives very soon, Jodi!
