"While I would have though that the majority of I-Pad Pros sold would be to hipsters and existing well-heeled I-Pad owners"
You're probably right about that. Unfortunately, Apple were very definitely trying to position the iPad Pro as a business device and direct competitor to the Surface, despite the fact that it's horribly unsuited to it for lots of reasons, so they won't be happy with just luring existing iPad users over - this was meant to be a major crossover device to re-open up the lucrative commercial market for Apple. It's pretty much failed to do that and just ended up being an iPad + version for the particularly well-to-do consumer.
