Windows 8 is not an over-the-air type of automatic update. It's something a user decides to go to buy and install. This is the type of thing where you _do_ want it to look at least a little different, otherwise the user will have the feeling they paid for "nothing". That's undoubtable one of the reasons that the Snow Leopard price was so low ($29 vs $129), even though I assume it was on the same order in terms of engineering effort.
