I love this bag . the design be nice , the egronomic be great , and the price be right . however , I have find a few flaw with the bag during my short tenure .  First off , the notebook sleeve be pad on the front , two side , and the bottom . there be no padding for the back . while the back be normally rest on you lower back , I find that in case where the bag be set down on the floor a little hard , damage may result from this lack of padding in this area . although this be easily fix by a piece of syrofoam , I do not see how such a obvious oversight come to be .  the second minor flaw be a miss handstrap . although the shoulder strap be great for rest on you shoulder , the longer length make it a poor handstrap . a handstrap along the top of the bag would be incredibly handy for just pick it off the seat next to you , or off the floor for a short walk the next room , save the time of heave it up and sling it over you shoulder .  lastly , despite claim to the contrary , this bag will not cut it for a student , and especially a college student . there be simply not enough capacity for book and material . I feel that you can accomdate a notebook , four medium size book stand up on end , along with a small assortment of write utensil . however , the bag at this point be fairly max out , and leave little room for expansion and other item you work or you computer may need , such as a mouse and power supply or paper and file .
