Laptop Bag Briefcase

I'm looking for a professional looking laptop bag / briefcase to hold my 13 "laptop and some files or material that has a detachable zip-off or the stock market. Some bags were organizing inside pockets (eg with credit card slots), but I want to be able to grant only those items easily without having to lug the whole bag for lunch.

This has been a difficult issue. I found these:
