(To be fair, the data is incomplete and may be inaccurate, though to my knowledge the entries for Apple devices are all correct). So it's not a given that the cited hardware dpi values would lead to higher CSS pixel ratios in the corresponding software. Apparently I forgot to link the page I meant: <http://en.wikipedia.org/wiki/List_of_displays_by_pixel_density> Regards, Maciej
