Do you remember how much fun they had with the size of the Galaxy Note? BGR,buisinessinsider,gruber,siegler,the verge,... The whole techmeme club. Then Samsung sold 5 million Notes in the first months.
A ton of films get trashed by critics and imdb then go on to be commercially successful. That doesn't mean it was a good piece of film. More likely it was accessible everywhere and well marketed.
But the lesson with the Galaxy Note was that many people want a device with a 5.3 in screen, and the critique was that people do not want a device with a 5.3 in screen.
Remember that Samsung sold the Note together with the Galaxy S2 (same hardware, smaller screen, higher marketing budget) and even smaller form factors.
Or, to put it another way: The lesson is that there is no "average consumer".
