Earlier quoted context omitted.
I'm thinking that if you're in the market for a $3600 Internet-connected fridge, you can afford and would just rather have the iPad. I don't know enough about the Fire to say whether it's a piece of garbage or not; all I know is that I have a bunch of iPad apps that I've paid for and Apple's ecosystem makes it easy to add another iPad and transfer my settings over.
Humans are pretty funny! Going off the usual price for apps ($2.99?), and a 'bunch' is probably about 25 apps, then replacing all your paid iOS apps with paid Fire apps would probably cost you $75. So ignoring anything else, a lot of people would actually value their $75 sunk app costs greater than the $350 difference between that iPad and the Fire. It's a pretty interesting lesson in humanity.
And there is always this one little app whose substitute would be perfect if only it didn't miss this one little feature.
