Re: moving things for no reason, that is bad!!!
Get with the program. Moving things for no reason is the entire raison d'être of the new UI paradigm. Many consultants in expensive suits promote the idea to "surprise the user" and "enhance the experience".
Because, once you have a product that does everything the user needs, it's the only thing you can do to maintain the appearance that you did some work.
Oh - that and breaking it, of course.
