This is an excellent case, and fits my needs perfectly.  It fits my 15.4" Lenovo Thinkpad T61 like a glove, and all of my essential tools and papers in the other side.  I wish I had known about it when I first bought my computer.  However, I do wish that it had padding in the laptop compartment.  Although the canvas is durable, it will not really protect against bumps and knocks.  I plan on getting a fitted sleeve for my laptop which I will then put inside the briefcase.
