I did my research before buying this case. I weighed the pros and cons of this case and many others like it. This is why it is the best:
1. Complete protection - This thing is firm on the outside, and has a memory foam cushion that hugs it in place for when it is zipped closed. There is no room for my macbook pro retina to move at all, and it is completely safe from zipper scratches and it seems like it could take a drop on its side and be protected. (not that I am trying this)
2. Convenience - This case has a great carrying strap, and can be used as a cover with its clear screen straps that keep the case semi-attached to the lid of the laptop. The fact that these are clear allows for them to not impede what is on the screen. When you are on a crowded train with a standing passengers bag shoved in your face, their backpack wont scratch the outside of your laptop if you need to use it. the laptop can be easily slipped in and out of the case when you want the Macbook pro to be free!
3. Quality/attention to detail - this case has a very high level of build quality. The fabric seems strong, and is water resistant. As mentioned before, I love the fact that the outside is rigid to protect the laptop and it has memory foam to hold it snug. There are also 4 little platforms on the inside of the case that slightly props up the laptop to allow for a little bit of air flow.
The only reason I would not buy this is if I was looking for something very low profile. This case is bulkier than some, but unmatched in terms of protection.
