Bag Suggestions? I am looking for a new bag as my current Lowepro AW 300 cannot fit my laptop in side. it is a great bag (might sell it if I find a good enough replacement.) I basically want a shoulder / sling / Messenger / Satchel (whatever you wish to call it.) bag. enough room to fit: Laptop (15.6") Camera (20D) 18-55mm 70-300mm 50mm (attatched to camera most times.) portable hard drive (could put in my pocket if need be.) some extra space for some paper work. I have had a look but cannot really find anything that comes to what I need. there is some backpacks, but It is for college, I just want something fairly simple, no bags that look over sized and stuff.
