Query: Protects nicely; very tight

Although advertised as a sleve, this is more like a zip-able briefcase. I was pleasantly surprised by how tough and protective the case is. Corner protection, often a weak spot in these designs, is exceptional. The thing provides a very nice combination of slim design and thorough protection. I'm not in a financial position to run Mac-dropping experiments, but I suspect this could take some very hard knocks.A few caveats:The fit is tight, and I would have some misgivings about overheating the MacBook by running it fully seated in the case, as this would tend to block the main heat vent. There is just barely enough room in the back pocket to get a wireless mouse and power supply. Great for transporting the MacBook; probably less ideal for running it seated in an open case, although this problem is going to be present in almost any case.
