To clarify, I wasn't advocating that we compare the mini display to the iPad 3/4. OP asked for examples of "worst" aspects of the mini display, so I told him if he wanted to see that, then he would have to compare it to iPad 3/4. In other words, I tend to agree with you -- the mini display only looks bad if you compare it to retina displays.
Apologies, I was trying more to speak in generalities than specifically to you (meaning when I said 'you' I meant 'one'), I just used your post because it was convenient as a way to discuss the whole comparison thing going on that gives the mini a bad rep.
I don't remember (and correct me if I'm wrong) any people talking about how crap the gen 1 and gen 2 iPads were when they were released, and now people on here talk about the "crappy" mini screen (but in absolute terms which I think is silly and dishonest), even though it's only when you compare the screen that it falls short, and I think the device is so much more than merely a screen, just as a car (in my poor analogy I used earlier) is so much more than merely its engine.
