Does anyone have the iFrogz Backbone iPad Case? I have their iPhone case and love the how minimal bulk it added to my iPhone 4S and the sort of smooth matte finish to it. Feels good, the entire phone is protected. http://www.ifrogz.com/product/IPAD2-BAK#overview It seems so many of the iPad cases add too much bulk for me or they leave way too much of the edges of the iPad exposed to potential scratches and damage. I liked the look of the Backbone coupled with the Apple Smart cover. My specific questions regarding it was how secure is the Smart Cover with the case as it seems many complain that the Smart Cover is easily disloged from the iPad and so many cases come with a cover that turns the iPad on.
