IMHO it was a paid placement, as is the Mac, as is most of what you see on the Sopranos. The folks that produce those shows are not fools and routinely approach those who would be "hip" to see if they will pay to have their products seen/mentioned as opposed to having their competitors'products/names seen/mentioned.
I agree. Most of these productions have a product placement group. Almost nothing branded shown on TV and movies is not paid for.
