So, I just got a MacBook Pro 15" for college (hooray for Apple Refurbished!) and I know that I will need a case. I want a messenger-bag style because it's easier to maneuver around a large campus (such as University of Minnesota Twin-Cities). It's also easier to get my laptop/books in or out quickly. (I'm not averse to a backpack if someone really thinks they're a better option) Using the MacRumors case buying guide, I came up with these four laptop cases: <http://www.samsonitecompanystores.com/webapp/scs/servlet/SItemDisplay?productId=258104&storeId=10151&langId=-1&pc=C30&pcode=> Samsonite Pro-DLX <http://sumocases.com/store/product_info.php?products_id=81> Sumo 15" Men's Professional Computer Case <http://www.timbuk2.com/tb2/products/bagbuilder> I can't post a direct link because it's build-your-own bag in a flash player. It's the Laptop Messenger, Medium size. <http://www.booqbags.com/s.nl/it.A/id.281/.f?sc=12&category=-112> Mamba Saddle, red <http://www.brenthaven.com/catalog-premium-pro-ii-apple.html> Brenthaven Premium Prolite II (Prolite II with a sleeve) Thoughts? Other recommendations? I don't want to make a bad decision because: a) This is a lot of money and b) I have to use this for 4+ years at college.
