(at around 47 mins) When the street vendor is examining the snake scale, the serial number she reads out loud doesn't match the number on her video screen (corrected in the 2007 "Final Cut" of the movie; the graphic now matches her dialogue). Additionally, she never removes the scale from the plastic bag in which it resides when Deckard gives it to her. There is no conceivable way that any microscope could produce such a clear image through plastic. We can only guess at advances in plastic and microscope technology by the time the movie is set.
In the "happy ending" Theatrical/International cuts, the credits play over the gorgeous scenery. In later Director/Final cuts, they play over a normal black background.
