Design
This product is a hybrid between a laptop sleeve and a laptop briefcase. Unlike a laptop sleeve, this product has handles and (unlike some sleeves) a zipper enclosure. Unlike a laptop case, it has no internal or external pockets for your power brick or other accessories. It is meant for modern laptops, such as MacBooks and MacBook Pros, with excellent battery life. It also has no shoulder strap or anywhere to attach a shoulder strap.
It is a small, handsome case, which is lightweight and feels confortable carrying by the handles. It adds about 1/2" to the width of the laptop when it is closed. Keep that in mind, because you will probably stash this case inside a suitcase or a larger briefcase when you are on the go.
Its external dimensions are 14.2" x 11" x 1.8".
Its laptop compartment dimensions are 13" x 9.4" x 1.5".
It is designed to fit 12 to 13.3" netbooks and laptops.
Testing
I tested this case with my white 13.3" MacBook and my wife's 13.3" MacBook Pro. The computers fit within the case perfectly, with a tiny amount of wiggle room on the sides.
Using Your Laptop from Within the Case
The case opens to a 90+ degree angle, which encourages you to use your laptop from within the case. This is very convenient when working on a train, plane, or bus. As a bonus, the case helps protect your lap from the heat of the laptop. The ridges on the inside's bottom, and the channels between the bubble-like padding on the inside's top, help channel heat away from your laptop. I did notice that the laptop often closed on the case's inner corner straps, when closing the laptop while it is within the case.
Recommendation
I would recommend this laptop case for students or workers who often travel without the laptop's power supply or peripherals. It's definitely appropriate if you often haul your MacBook to the local coffee shop, or use it while commuting. Since it is a sleeve, you'll likely use it within another briefcase or suitcase, especially if you want to travel with a power cable or a mouse.
