I would love it more if it had some shallow pockets either on the inside or on the outside. Small things like pen, pencil, cell phone, chap stick, granola bar have no place to go but to get lost under my computer, hot novel and note pad.
Right and left outside side pockets could work for replaceable items.... making one to fit a small water bottle would be excellent.
As to inside pockets - there really needs to be a shallow one opening at the top edge to accommodate tickets, possible...
