Yeah I'd agree with that stance.
I know people often talk about Android vs Apple sales figures and market share, but its not quite as clear cut as that. Apple might not have the biggest share of the pie, but they still have a decent share and they market themselves as selling premium products, regardless of whether you feel their premium is lacking compared to what the competition offer.
There is also the fact that so many people are 'locked' into Apple. Thus you won't want to switch to something else, even if it has a better display. The person who does see all the hardware differences is likely to buy where they feel they are getting the best value for their money, rather than sticking to one system.
Just as Rilot says, currently you can buy an iPad Mini, but at the sametime for not much more, you could buy an iPad with a better display. That however hasn't stopped people buying them by the bucketload.
