Brenthave, Brenthaven, Brenthaven. I've traveled all over the world with my Brenthaven. It goes to class with me, carries my hard drives, Powerbook, iPod, camera, books, you name it....that sucker expands, even though it doesn't look like it does. It has a slim profile if almost empy and it is built like a rock but still looks great. The best pack I have ever owned...period. I used my 15" version for 2 years, I liked them so much, I bought another one when I upgraded to the 17" and then bough a shoulder case on top of it. WORTH EVERY PENNY!!!
