How is Blu-ray the biggest jump in video quality?

I believe the jump from VHS to DVD is far more significant. Not only was the quality jump more noticeable, but the advantage of DVDs is seen in many ways such as: no rewinding, typically error free picture, extra features, and less mechanical problems (no eating tapes). Blu-ray just has a better picture with a few add-on but IMO frivilous features that we certainly don't need to enjoy the movie.
