I know they haven't released the Incase yet, but does anyone know if it's good? I've heard from the 3rd gen that it badly scratches the back of the Ipod, and that it's impossible to take off. Do you think that would change with the 4th gen, esp. because the back is flat not curved? If the Incase is not good, what is the best alternative that is similar, but doesn't scratch the back and is possible to remove? Also, is the Belkin Grip Vue a good looking case, and is it good quality as well? Which would you prefer?
