I'm wanting to replace the old backpack that is my bob, its a basic school book carrying style and looking a little worn in spots. I want something like a plain black laptop backpack though my laptop I carry in a slipcase and its about book sized in the case so it doesn't need to be laptop specific. I would like a zip open front flap with at least three larger pockets behind it to put things like my scanner and other handheld held radios. I really like the Voltaic solar backpack, but don't like the battery pack being right in the front and I bet it won't hold up long term as its probably more a gimmick than quality. Any favorites or suggestions?
