Laptop backpacks for traveling

I've been looking for something to use for traveling around with my laptop, in particular I want to take it along when I go hiking. It's nice and light weight so hiking with it would be very easy. This has lead me to browsing through the best buy deals at www.buy.com. I really love the looks of the Tommy Hilfiger Joshua Tree Backpack, a nice rugged looking backpack made for laptops, but I am leaning toward the Targus Notebook Case Backpack because of the multiple compartments and the styling matches the bag I had got when I flew down to Las Vegas, so they would make an excellent travel bag set together.
