What item is this?

I think it is a PB support-thing, but I don't know the name for it.

got this one for my 17" - using it right now as a desktop with external keyboard and mighty mouse - screen is on an excellent level to use PB as a desktop - go for it, is a great buy, absolutely worth it, made from the exactly same material as the PB's body ...
