I have ample evidence that I'm a mostly-sane observer. Is everyone who disagrees with you insane? The 1.5 cm is a huge difference for most people being able to comfortably hold it the way I and most people I've seen seem to prefer to hold the Nexus 7: in portrait mode, with my thumb on one side and my four fingers on the other. I found a book that is the exact width of the iPad Mini (and it's lighter) and it hurts my hand to try to stretch it that way. I'm sure some people with large hands will be able to hold it that way, but my opinion (I don't think you're insane if you disagree) is that most people will not be able to do so comfortably. In short, 15 mm isn't a large difference in the abstract, but it's quite a lot of difference "at the margin," which is what I think we're talking about. I think it takes you from dimensions that maybe 80-90% of people can hold comfortably in the way I've described to ones that perhaps 10-20% of people can.
