I travel everyday on a train to college. I would like to bring along my 15" Pro on some of those days. What would you guys say is the best way to carry it? I don't like laptop bags. I'd rather slip it into my rucksack with my folders and iPad. Would one of these provide enough protection? http://store.apple.com/uk/product/H5198ZM/A/Incase_Neoprene_Slim_Sleeve?fnode=MTY1NDA2Ng Thanks for reading!
