Apple made iPads available at the product launch for journalists, but they haven't provided any for studio photography, forcing every newspaper and magazine to use the same product imagery. We were able to help Macworld differentiate itself from the competition by creating a computer-generated set of iPads for its April cover.
The editors freely admit that they had limited access to a preproduction iPad, but their 10-page cover story is very comprehensive, as you'd expect from Macworld. Highly recommended!
