I got mine (the European tin edition, no briefcase) a while back, and it absolutely totally rocks! I first watched the final cut, which is an altogether brilliant film. This is how Blade Runner should be, IMHO. George Lucas, take note on how to revisit old films

It is the old Blade Runner, but better. All the small details that were fixed, without changing the film (Greedo shot first, anyone

?).
It is amazing the way this 25 year old film doesn't feel dated in any way.
The I watched the marvellous Dangerous Days documentary, clocking in at around three hours or so...
Then most of the other supplementary material, including Philip K Dick interviews.
Finally I watched the workprint with commentary track. That was interesting as well, but not as interesting or different as I'd have thought.
All in all, the tin, with the fold-out digipak of all the discs, and the frame from the film, is absolutely gorgeous!
One of my best ever purchases, especially at around 25 Euros pre-ordered from Play.com.
