I got my 12 inch MacBook and dropped it to the floor while I as using it. It broke and I sold it. I'm thinking about buying a new one, and if I do so I'll probably want to have some protection to prevent a similar accident. Most protection cases are either thin hard cases. Thick ones are mostly cases which you have to take your MacBook from when you use it. What I am looking for a protection while in use. I thought Twelve South BookBook looked good because it looks thick and you can use it without taking it out. But the case looks really loose, and I couldn't figure out how it holds the MacBook in side. The monitor looks to be held by the straps, but the bottom part looks to have nothing attached to the case. In short, - What is your recommendation for protection while in use? - Does anybody here has a Twelve South BookBook? How does it hold your MacBook?
