I need your help. I need a new bag to bring on business travel. I've given a backpack a chance and it isn't doing it for me. I've got to get a messenger bag and quickly.

What I'm looking for is:

Holds my 15" MacBook Pro
Has a pocket on the outside front flap

That is about it. I don't ask for much. *grin* The outside pocket is a must. It is the only reason I don't like the Timbuk2 bags. They rock other then that, but I need that outside pocket to open and drop things in.

So give me your links and suggestions because I can't find anything that does it for me. Help me out!
