If you are looking for a secure and nearly indestructible way to transport your laptop and other items, Zero Halliburton has a very viable option with their S1-SI Premium Slimline Attache.
After using Swiss Gear and Timbuk2 notebook bags for years when travelling, last month I was looking for something a little bit different. With the new Apple MacBook Pro with Retina Display not having a Kensington lock slot (the craziest flaw from my perspective for the Retina MacBook Pro is the lack of any securing mechanism), I was looking for a case to better secure my notebook while travelling. (Though since then, after-market solutions for locking the new rMBP have been announced from third-parties.) Plus with travelling to Nicaragua in July I was looking for something all-around more secure too.
With the searching for a new travel case, it came down to choosing between the business/notebook cases offered by Pelican and Zero Halliburton. In the end, based upon the prices, sizes, and features, the Zero Halliburton S1 won out as something suitable and was ordered.
The Zero Halliburton S1 Premium Slimeline Attache is constructed out of 100% anodized aircraft-grade aluminum, features a lined interior with organizer file, ergonomic handle, triple digit locking mechanism with slide latch, and is constructed in the US. While the heat-tempered aircraft-grade aluminum is highly reliable, it puts the weight on this case at about 3.6 kilograms, or the weight of more than two of the new Retina MacBook Pros. The dimensions on this case are 45 x 33 x 7 cm, which should be able to accommodate most 15-inch or smaller notebooks.
