I've had the Mission Photo backpack for about a month now, and I have no problems with it. In fact, its great, fits a 7D, telephoto, and two other lenses; with room for at least two more, and it is padded so well I never worry. It doesn't have a laptop sleeve, but you can easily slide a 13 inch macbook in the back of the camera compartment. Front organizational pocket is very nice. Literally the only problem I've noticed is the tripod strap loosens too easily but the board straps in conjunction make it so its not a big deal. Haven't had the chance to try it out in any weather yet, but the rain cover seems solid, I don't really have any fear about when the rain and pow starts to fall.
