I also have a Targus backpack. Actually, I think mine has a fair amount of protection. In addition, the part of the backpack that is against my back is padded so much that I think it actually acts as a spine protector.
Here's a link to the one I have. I can't remember where, but I got it online.
I had a Targus before and the Boblbee is extremly comfortable and they offer more accesories than you'll ever need. It's a bit pricey, but I got an awesome discount when I visted one of their custom retail shops.
It only holds laptops up to 15" though, but they do offer a couple of different size packs.
