Familiarity: I've put it through the wringer
Since getting the Classic Navy Patagonia Arbor backpack, I've used it almost everyday and it has stood up to my abuse while also keeping my laptop protected. It has a classic look and utilitarian construction. The two zip pockets are crucial for keeping small stuff separated and easy to find. The main compartment is bigger than it looks - with a 15" computer and an ipad in the laptop sleeve, there's plenty of room for my headphone case, camera, down sweater, extra layer, etc.
