MacNN has reviewed a group of seven iPad cases, in part one of a series of reviews. The first collection falls into a basic category, with models that simply cover an iPad and secure it. The first reviews look at the Acme Made Slick Case, the NewerTech iFolio Black, the Waterfield iPad Ultimate SleeveCase, the STM jacket iPad, the Targus Crave Sleeve-iPad, and the Targus iPad A7 Sleeve. These have prices as low as $25 and as high as $100.
