Touch sensitive on the back-side
Apple has a few patents pertaining to have touch sensitive areas on the back side of devices... http://gizmodo.com/259271/next-gen-ipod-patent-has-touch-surface-on-back
If you think about the way you hold a book or magazine, you do naturally place a few fingers on the back side to help support the object. It would not take much to say just swipe your finger to scroll up or down, or two or three fingers for other actions.
While it may not make a good input system for entering text, it could very well remove the need to constantly reach for the front surface to interact with it.
I'm willing to bet the tech for the magic mouse, will make its way onto the back side of the apple tablet for convenient and comfortable interaction.
