Stephen Baker, Vice President, Industry Analysis for NPD:

>Shipments are not sales, seems like a pretty simple concept to grasp, but it’s apparent from the hysteria that has erupted over IDC’s release of their Q1 tablet shipment data that most of the blogosphere still doesn’t get the difference.

His entire post explains how shipments are a meaningless number and how sales are really important. Baker seems to be condemning people who say that Kindle Fire sales are not good because they shipped far less in Q2 than Amazon did in Q1.

This is funny to me because a [quick search of “npd shipments”](http://www.bing.com/search?q=npd+shipments&form=APIPA1) shows you just how much NPD reports about shipment numbers…
