The iPad 2 is just too pretty to leave the back uncovered.  We too at outfitYOURS.com waited in line all day to buy our new iPad 2 and bought the Apple Smart Cover for iPad 2 because of the new technology and cool colors. Within hours, we realized the need to cover the back.  Speck quickly solved the uncovered back problem with the Speck Smartshell case for iPad 2.  This iPad 2 case is the perfect iPad 2 back cover that allows you to continue to use your Apple SmartCover and to not have to cringe every time your iPad 2 is thrown on the table.  The Speck Smartshell case includes a magnetic back that allows you to fold your SmartCover behind your iPad 2.  The new Speck SmartShell Case for iPad is simple but perfect for your iPad 2 and SmartCover!
