Hey guys! I went to Powermac Center yesterday and saw that they have new cases for the Macbook Aluminum. Would you recommend that I get one? If so, which one would be the best choice among these: 1:Macally Leather Protective Shell - for 13" Aluminum MacBook - Black/Redhttp://www.ciao.com/Macally_BookShell_MacBook_Leather_Protective_Cover__15161961 2. Speck See Thru Satin Hard Shell for macbook---it comes in black/red/purple http://www.speckproducts.com/products/seethru-satin/macbook-pro-15-new-black-keys/164 And would anyone know if these are available in Digital Walker?
