Hello, I just stumbled upon the site a few days ago while researching which bag to get. I've never been portable before, but I recently purchased a Macbook Pro and that has caused me to reassess the situation (i.e., how best to carry a laptop, notebook, pens, magazines, etc.) Jack Spade bags always keep turning up and I do like their style, although, I'm not a fan of loud velcro closures. The magnetic snap of the Waxwear line are more appealing. Needless to say, the Jack Spade website is useless in determining what will work for me. So far, I've come up with the following list of potential Jack Spade solutions: Tech Field Canvas Bag Nylon Canvas Field Bag Waxwear Laptop Field Bag Waxwear Computer Field Bag Nylon Canvas Computer Field Bag II Drill Nylon Computer Feild Bag I came about this list via Jack Spade's website, Zappo's website, and Google. I grasp the differences between Waxwear and Nylon, but am not sure about Drill Nylon. I assume it goes Nylon, Waxwear, Drill Nylon in terms of ruggedness? Secondly, are any of the bag names referring to the same bag (e.g., 'Nylon Canvas Computer Field Bag II' on Zappo's might be the same as the 'Nylon Canvas Computer Field Bag' on Jack Spade)? It's quite possible Zappo's doesn't have the right name on their site. If someone would kindly shed some light on what the major differences between these bags are, that would be wonderful and it help tremendously with my purchase decision. Thanks! Edited to add: I probably won't be using any sleeve that comes with a Jack Spade bag. In all likelyhood, I plan on going with either a WaterField SleeveCase, Tucano Second Skin, or Colca Sac. I'm still trying to decide. I mention this, because I know at least one or two of the Jack Spade bags above contain a sleeve.
