I'm in the market for a messenger bag that will hold my powerbook as well as my Wacom Intuos3 6x11 (16.5" x 10.3" x .6"). I've seen a few around that match the measurements, some even larger than necessary. I'm really trying to find one that is not too large, but just large enough to hold the tablet comfortably. I was wondering if anyone here has any experience with bags and Wacom tablets. Thanks!
