Yeah, I'm genuinely surprised by some of the visceral reactions, too. I bought the Mini 4 in September of 2015. It was $499 for the 32gb model then. It's been an excellent tablet for my needs, and I will get the 64gb Mini 5.
There are a lot of armchair CEOs in these forums and now that the new iPad mini (5) is a real product, a lot of wish fulfillment has been torn down, which tends to really ramp up the discord. Literally, the same thing happened when the Mac mini was announced, and still goes on to an extent in certain sub-forums.
