Stolen from MattSinger. He limited his list to Blu-Ray, but as a recent convert to Blu-Ray myself, it would make for a terribly short list. My lust for Criterion editions began back in my Laserdisc days, which is why you'll see some titles here that are not available on DVD or Blu-Ray. This is a respectable listing... but one can never have too many Criterions. I think you know what I mean.
Consider all titles to be on DVD, unless otherwise noted. They are arranged by spine number, because for some reason I wanted this to be really hard.
