"but this[gruber's] article is incredibly stupid, for exactly the reasons he posts about" Gruber's article is a counterpoint on "PC manufacturers are dominant in the tablet space", and the idea that NPD were incorrectly attributing the "number 2" player to HP. Naturally the iPad comes into discussion (and yes it's smart to remove the iPad when trying to look at the rest of the market.) However NPD were publishing conclusions that aren't reasonable in light of the fact that the Kindle Fire and B&N Nook are selling very well in addition to the dominance of the iPad. By some reputable estimates the Nook is selling well in excess of HP. (To the tone of 15x the sales of HP.)
