I agree. I often use the BB as my clothing bag for 3-5 day trips and really love it. You can see my setup here.

But yeah, packing cubes really help! For example, if socks are in the bottom, you'll pretty much have to pull out all of your items to get to socks. With packing cubes, you still have to pull things out but it's oh so much easier!
