I bought the Koston pack after I came to the realization that the blown zippers on my old, haggard pack weren't going to heal themselves. The Koston has everything I need. The laptop fits my 15in Mac perfectly, and the little fuzzy pouch tends my iPod like some sort of a marsupial. The straps are super comfy and the front divider pockets keep my OCD tendencies in check. The pinstripes are dope too. Buy this thing.
