(Or you'll pass a store on the commute every day that you would pick stuff up at if you had the cargo capacity.)
Another option might be a frame bag. I have been thinking of getting one. Only thing preventing me from pulling the trigger is that they are usually smaller than my current 23L backpack. Also don't know how easy it would be to take off the bike. But I think its just a few velcro straps that hold it on, no?
