I am looking for a backpack and and wondering if anybody has any ideas.. I am having a hard time finding one I like. I want something that is going to hold up. I carry around my rMBP 15 and my 9.7 iPP, and all the Chargers and adapters necessary. I also always have a couple of screwdrivers, pliars, and a c wrench. Last year I bought a Cococoon Slim. From a design perspective I love the thing. From a quality perspective it is garbage. The first one had a broken strap within weeks. Cocoon sent me another, and it suffered the same fate. http://www.cocooninnovations.com/product_info.php?product_id=244 The North Face Microbyte looks like like a great pack, but it won't fit my 15 MacBook. So basically I want minimalist. What do you guys use? Any I might like?
