Seeing Megs' birkin last week in NY got me thinking about the 30 cm size, having up to now been a fan of the 35 cm size. Anyone have any experiences with "switching" sizes or strong feelings toward one or the other? (ozzysmom, I know you are out there! please weigh in). As you might expect, given that overly analytical nature of mine that you have come to love (or at least, be amused by), there is a poll attached to this.
