I've become an avid fan of little accessory bags as a compliment to my laptop bag. They help keep my usb keys, security tokens, video dongles, pens, business cards and other assorted tech miscellany neat and tidy. The pouches from Tom Bihn with the clear plastic front are probably my favourite, but I've also used the minis from Lexie Barnes and the cachets from Coakley.
But I don't really have anything for my cords. The power brick on the MacBook power cord is so unweildy - I just kind of bunch up the cord and wrap a rubber band around it. Not particularly classy. However, I just found out about the Cable Stable from Skooba and this might be a good solution.
You can even stash your netbook in one side and still use the other side for cords and other accessories. Sweet.
You can get more pics and details on the Cable Stable at Skooba's site. The Cable Stable retails for $39.95 US.
