nSignia Exotic Leather Cases for Dell Axim Models I would choose the nSignia Black Eagleray Leather Case Wallet Style for Dell Axim X51(v), because it's beautiful (so much so that I'd need a case for the case!) and it's the color of my Alma Mater. With this case I wouldn't have to carry a wallet. The three credit card slots and multipurpose slots take care of that. and I just happen to carry three SD cards, 1 in the Ax and 2 in the case!
