Does anyone have the Skip Hop Grand Central diaper bag?

I liked it when I saw it in person at Buy Buy Baby - it was nice and light without anything in it. I registered for the chocolate color. But I cannot get the idea of a Petunia Picklebottom Boxy Backpack out of my head either! Which would you prefer? I'm a FTM with baby due in June so I'm clueless!
