In the official website, I was able to confirm my suspicion that Carrie upgraded her laptop. You can now even browse her
EDIT: Gadgenista argues that since Carrie's laptop doesn't use the Magsafe Adapter and does not have an iSight, it must be a G4, and therefore a Powerbook. But the website does say that Carrie is using a Macbook Pro. Oh well. The above photo was swiped from Gadgenista.
