tough choice! personally i think you should get one right now. i say that b/c a lot of companies haven't rolled out their spring lines yet, so chances are in the next 2 or 3 months you'll see something else that you'll go gaga over, or even the same bag in a different color.
that being said, i'm not sure which one i'd pick. i think the color of the paddington makes it seasonless so i think i'll vote for that one.
