The Serra North-South design trolley in black is a super-lightweight wheelie case that holds up to a 15" laptop, deep within its waterproof compartments. With oh-so-fashionable quilting, the clever layout makes the most of the space and will hold files, folders and even a small change of clothes along with your laptop and day-to-day items, whilst keeping your laptop and cables dry and safe within its thoroughly padded compartment.
PROS: I love this tote! I bought an earlier version about 1.5 years ago, and it is not only great looking, it is great for organization. It is narrow enough that you can roll it down the aisle of all but the smallest airplanes. I definitely have fit mine under the seat of most planes with no problem at all, that was important to me and one of the reasons I bought this style. I don't know if the new models are bigger than mine, but I don't think so. It will stick out an inch or two from under the seat, but none of the flight attendants have even given this a second look. This trolley has held up beautifully - even through Michigan winters being rolled through snow and slush. I use one of the side pockets for my laptop cord and the other for a small Totes umbrella. I'm thinking of buying another case just to have for the future, because I looked long and hard for one that was this perfect. By the way, Luggage Pros is an amazing store - the people are very friendly, responsive, and professional, and the prices are great. I highly recommend this site for all your luggage needs. (And this is not a paid endorsement LOL)
CONS: I wish that the rear of the case was an actual zippered compartment. On mine, it is simply for sliding over the handle of another piece of luggage, which I rarely if ever do.
