Damn, guess I'm going to break down why I want a bag that carry's what I listed. The bottles of water are not for the journey, they're for drinking at work. I don't exactly work with the cleanest bunch of people, and would prefer not to buy water. As I mentioned earlier, I work in a professional office, so a bladder would be weird to have on the desk, and I don't have a clean sink to wash my dishes in.
As for the laptop, I use it as a courtesy to my customers to bill insurance companies direct. I could always ask them to pay first, and then have them submit a receipt to get reimbursed later, but that is where I start to lose sales. I also use my laptop to order product over out distributors website. We don't have much in the way of technology here except for a phone from the 80's, and a fax machine.
Anyway, it looks like I haven't really gotten much in the way of actual recommendations of bags, so I guess I'll stick with what I have now, and work with it.
