I was having a hard time finding a backpack large enough for my Toshiba Qosmio. The laptop is thicker than most 17" models, so it is real snug in the designed pocket. Also, since the notebook is thicker, the zippers rub the corners. I don't travel alot, so I am using the main compartment instead as there are plenty of other pockets for accessories. I think a thinner notebook would fit very well in the bag and it offers more cushion/protection than my other option..Targus XL.
