I know, I know! This has been asked a million times, but I am looking for something that can hold the following: 15" MacBook Pro Charger with Extension Mouse (Typical size, nothing huge or tiny) and lastly, binder and books I have a bag that is awesome to fit everything, but when it comes to adding in a binder or book it doesn't fit very well... Im not looking for something huge with a billion pockets, more looking for something that is as if it where made for the MacBook Pro carrying student! Essentially as small as it can be while still fitting everything. I love backpacks and messenger bags! Thanks!
