With specific reference to your comment about the Type Cover, my personal preference would be to have MS offer a keyboardless Cover with every Surface device and let the customer buy the Type Cover.
I had the same thought. I would always want a type cover to use away from home or office plus I think it provides good protection for the screen. For those that can't afford the type cover right away or don't plan on ever needing one, than some sort of free protective cover that would ship with the SP would be a good idea.
