Looking for a laptop bag and I have always used army surplus bags and still have my old bag from grade school, but a laptop would not be secure in it so I have come a cross the M-51 ENGINEERS FIELD BAG and like it.

It has a large inner pocket and one for a laptop, pen, note pad and small pockets for the power converter. on the back is a map pocket and tool pockets with a bottom/side ziper and top flap. bottle pocket on the side as well. carry handle and strap...
what more can you ask for??
