Now that I'm moving into a corporate world, I've decided it's time to get a more "professional" tote than my Osprey backpack The only laptops My range is about thirteen" as I find carrying anything heavier too much to consider portable. This portfolio packs a punch. Lots of pockets, sometimes I feel like there are too many because I keep opening the wrong bag or I can't remember which bag I put something in so I'd like the labels to be different maybe there are some kind of lanyards on one or the other Sturdy and held up well in this crazy spring weather in Chicago. We've had temperatures ranging from 40 to 80 degrees, rain and drought in just two weeks. Chicago I tell you! My 2010 13" MBP fits nicely in ei a simple laptop bag without a snail. I walk around a lot and don't feel like lugging it around on my shoulder all day, along with some books, a Hobonichi planner, and my pencil case. Shoulder strap It's not that easy to set up and I still haven't quite figured it out. There are buckles on both sides in the middle - one is static and the other is adjustable. But the adjustable buckle doesn't make the strap easy to put on, so I won't be able to adjust it to a comfortable length for the rest of my life. The detachable strap is otherwise solid. Another issue is the clasp that holds the two handles together. It's not long enough, so instead of closing it with one hand, I have to grab the handles with both hands before I can press the button. Overall this is a great briefcase that can even be used with 13 inch laptops. But the shoulder strap and handle buckle need to be improved better and more convenient.
