I skimmed all that and don't know what point you're trying to make. Twenty years ago, it was "hurr durr, Apple is so small and unsuccesful, they don't know what they're doing". Now it's "Apple is so large and successful, they've lost sight of what they're doing". OK.
The iPad Pro doesn't cost $2700. I imagine the median sold iPad Pro is around $1100, maybe less. I'm not even sure how you would configure it to $2700, but I assure you almost nobody does. Yes, if they really need as much internal storage as possible (which, probably not), they might be spending a ton more.
There may be some people arguing "it does what I need", but I don't see that a lot in this thread. I also don't see Tim or Craig making that argument. If they did, why would they keep doing significant changes? They just introduced a major UI change to multitasking three weeks ago! You think that's Apple saying "it's already perfect! Wrap it up, we're done"?
