This has just exactly what you need and none of what you do not. A seperate specific, internal, and specially padded bag for your laptop embedded with the rest of the backpack. Supplying secure carriage for your laptop, but also allowing for books, folders, papers, or whatever within the main compartment. It also sports exterior pockets of various sizes, one with mutiple storage pockets for say a PDA/Calculator, pens and pencils, etc. The straps are nice, including a waist strap for those worried about your bag slipping. Very highly recommended. My Dell Inspiron 4100 fits just fine.
