I've always assumed though that he turned as a young man, and Shaw's force ghost always irked me, seeing this old man who is Darth Vader wearing Jedi robes (where did the old darth vader get it?)
I was skittish and worried about the change with the 2004 SE and was rather indifferent to it until last week. After Revenge of the Sith, I want Hayden to be in ROTJ and not Shaw, it just works much better. Besides, Lucas' rationalization that Anakin only gets to keep his young form (before his turn) is really no worse than the previous rationalization of the older Anakin being the force ghost. It's a matter of how you look at it, but given you guys have made it a mission to attack Lucas about all the changes he's made, It's not surprising you are all blindly following the old version of 'reality' despite the fact that it's really no better than the new one.
Wait, let me backtrack, the new version officially works better now, after Revenge of the Sith.
