i basically figured i can put my laptop/camera/zune/snacks/books in the backpack part, clothes in the square part and be set.
Plus it looks like it will be comfortable wearing as a backpack while trying to lug two other big *** suitcases through some strange *** airport.
the fact that its a roller bag is almost incidental, but i am sure at some point it will be a bonus....probably on shorter trips when i wont be wheely'in other full size suitcases.
It was expensive, but fuk... luggage is cost a shit ton.
Least if anything ever happens to it, they be replacing that shiz or fixen it for teh free.
