As per the title, I am looking to get a backpack for my T40 Thinkpad that doesn't crease/deform the shoulders of my suits. I currently use a STM Medium Eclipse (http://www.stmbags.com.au/mediumeclipse) and the capacity, features and construction are wonderful, but the shoulders of my suit get squished and I forever look like I just got off a redeye.

So I am considering getting either a Tumi Laptop Brief (http://www.tumi.com/business_laptop_...?modelid=57314) or another backpack that won't crumple the suit. I have heard good things about the Booq Boa XM (http://www.booqbags.com/Detail.bok?no=363), anyone have one of these or a recommended backpack?
