I spent forever browsing online for the perfect laptop case. I knew this Thule case was the one I wanted, but I wasn't sure how the sizing would match up with my laptop. I really didn't like anything else I saw except this one, so eventually I bought it. Luckily for me, it fits perfectly!
About the case: I love that it's sturdy and solid, though I wouldn't categorize this as a hard case. The zippers are great quality and have a bumper of sorts on the inside of both the top and bottom parts to prevent any nicking of laptop edges. You can use your laptop in the case, but some ports may be obstructed by the partially-elastic corner bands.
