Sony introduced a Flash-based movie and TV show repository today called Crackle that is meant for GoogleTV. The good news is that it works well on Mac as well and there is some compelling (and lot of not compelling) content on there from Sony Pictures and Movies.
Obviously because it is Flash based, it doesn’t work on iOS devices (haven’t tried with SkyFire) and it will juice your processor on your Mac, but free full length high quality movies? Hard to argue with that.
Update: commenters say it works with Skyfire!
