I recently decided that the reason I don't like any of the laptop bags I've ever tried to use is because they don't have enough pockets. Cables, adpaters, and everything else ends up in a big wad at the bottom of my bag, which drives me up the wall.
I made one that seemed to fit my somewhat picky specifications, and published a guide on how I made it. Hopefully it will come in handy to someone else out there who's as finicky about their bag as I am. (I hope they like Velcro.)
