I had to reinstall Windows on a new system. I'd forgotten that I'd already authorized iTunes on it, so it was never deauthorized. For the heck of it, I just reauthorized it (with the new install) and it still says I am only using 1/5 authorizations. Is 5 the total? Does that mean Apple's authorization thingee is smart enough to know it's the same system, even though I forgot to deauthorize, and the install is clean? If so, I'm impressed! I mean I hate activation DRM, but...well...yay!
