I ordered the Custom Commute Laptop Messenger Bag from Timbuk2. Only experience will determine if this was a good investment .... I usually only carry around 7-10 pounds of stuff, so weight should not be an issue. I'm concerned with quality and if things inside will stay dry .... Looks like a good possibility, and since we don't have a lot of rain here (only around 12 inches/year average), and I do not go out in the rain much at all, that shouldn't be a huge problem.
