Beefing it up towards something that is capable of serving as a development environment, as quite a few people wish for here, is fundamentally incompatible with that. Wanting a touch Mac is of course well and fine and understandable - but the iPad cannot become that without killing what makes it special in the first place.
Maybe there is a way to expose more power through iOS' user interface without adding noticeable complexity - but if there is, Apple has not found it yet. A good chunk of enhancements have either made things more complex — the "just stuff another button into the share sheet" school of thought seems prevalent — or led to features that are wholly invisible and undiscoverable.
Multitasking is a prime example: I end up using my girlfriends iPad Pro about once a week, and for the past year I have not managed to internalize how to reliably manage split screen modes and the like.
