I am not sure if you like any of these bags, they seem a big gaudy to me.

I personally would prefer to get a slipcase and then choose any bag/backback I wanted. This way, I am not restricted to just 'notebook ready' bags.

 

forgot to mention I ride my bike to school, actually I'm not really a patient person... I really like the grab and go Idea. Agressive one you can say .
