Tablet Shipments

Sarah Perez, reporting numbers released  by NPD:

[T]ablet PC shipments are expected to grow from 72.7 million units in 2011 to 383.3 million units by 2017.

Okay, so the tablet market is going to grow. They'll ship more tablets in 2017 than computers in 2011. Great. The thing I don't understand is why everyone is so hung up on shipping numbers. Shipped is not sold. Give me the sold numbers, please.
