Anyone is free to discuss whatever they like --
especially if they don't own the devices yet, because discussing the devices' strong and weak points can help them make an informed purchase decision they will not need to regret later on. If discussing gadgets were only permitted for their owners, online IT forums would be instantly reduced to 0.000001% of their current content. What a perfectly ridiculous idea.
It will be extremely rare for
anyone to be possessing both iPad Air and iPad mini Retina -- most people aren't millionaires, and the monthly income of most people on this planet is lower than the price of an iPad. However, lots and lots of people have been reporting over the last few days, just as quoted in the sample above, that they took a look at the same pictures/websites on iPad Air and iPad mini Retina, for example in an Apple store, and that the mini's screen struck them as
distinctly inferior compared to the iPad Air screen.
