Not the answer you want - but I think you should buy a cheap netbook to travel with.
why? the 13'' macbook is fine to travel with. I would get the speck hardshell, I had a black satin see-thru and I thought it made it really sharp looking. Now I have a clear speck case for my 17'' and it also looks nice on it. The case really protects well and doesn't add much bulk.
Can the hard shells even prevent damage from being banged around in a backpack? Wouldn't most of the damage come from it being shaken, dropped, or dust. I would think the shell would only help prevent scratches.
