Well, I'm just glad I've got the OOT in widescreen on VHS.
Lucas explains why in the commentary. Anakin Skywalker died when he became Darth Vader. "The good man who was your father was destroyed" His spirit appears young because it was his last true form. Obi-Wan and Yoda were good there who lives so them as old people was there last true form. If you think about it this change makes sense. Logically if his spirit was the way he died in the end he would not have hair, skin, or limbs.
