two of those results are just briefcases, the one has two elastic straps which will slow down your laptop as it hits the sidewalls with the charger floating around in there hopefully not doing too much damage..that seems risky still. i'd rather have a sleeve inside of a bookbag/messenger bag. if you want the hardcase for absolute protection just know you don't get it without a product that focuses on the deceleration of it's contents.. like a pelican case.. but they're more than I think most would spend.
