I wanna get a new case for my iPad and now I'm interested in these Leather Case with Touch Pen Snap Ring for iPad and Soft Protective Bag with Dual Zipper for iPad But I don't think I need to buy 2 cases at the same time. Moreover, they are different styles. The first one is made of lether and the second one looks like a bag. Which one would be more convenient and practical? I cannot make my decision, any ideas?
