I have Jack Spade's Field Bag in black canvas from the Greene St. line. The Field Bag is 2" deeper than the Day Bag, and I fill this added space with: "¢Â 12" PowerBook G4 in Timbuk2 Laptop Sleeve "¢Â zippered bag of cords and peripherals "¢ Periodical of some sort "¢Â iPod + in-ear headphones and wired remote "¢Â wallet "¢Â mints, lip balm, Aleve, business cards "¢Â sunglasses in hard-sided case "¢Â car keys Most laptop bags on the market are designed for machines quite a bit larger than my 12" PowerBook. And most of them look like they were designed to carry laptops. If not, most of the ones I have looked at are far too bulky and infested with extraneous pockets, zippers, and clips. Since I don't always carry a laptop, I prefer to drop a sleeve into a bag rather than carry a bag set up to carry a laptop all the time. I upgraded to this bag from a Timbuk2 messenger bag, size large in waxed canvas with add-on strap pouches for cell phone and iPod. I like this bag but it is a little too casual and young for me now. I wanted something that was not multi-colored, smaller, laid flat, was sleek and simple and designed in such a way that I didn't have to carry gadgets on the shoulder strap. I work as a freelance graphic designer/art director, an industry renown for relaxed dress codes, so I definitely did not want a briefcase, but I wanted something a little more upscale than my old Timbuk2 gear. The Jack Spade bag is the only bag I've found that is designed for pretty much exactly the way I use it and what I carry in it. I would like one with a little more space, but until then, this is the perfect bag for me.
