WRT drawing, specifically: no, they dragged their feet on introducing a pen/stylus for years. They insisted it be a "touch-only" device (Wacom's patents on display digitizers surely did not factor in /s), which sucked for those of us who couldn't afford a Cintiq, but who had a perfectly good iPad 2 lying around. There were several valiant, if flawed, stylus efforts befor the Pencil, but with awkward connection, pressure, and power solutions, they were DOA.
My complaint is that the idea that the decent drawing experience that we have now was part of Apple's master plan for the iPad is incorrect. They resisted it purposely because the iPad was never meant to be a creative device. The issue wasn't limited to visual art; people who wanted to use iPads for its other major creative application - as a music controller - had to use a number of hacks to break it out of the Garageband ghetto.
The core issue is the hobbling of promising hardware because it doesn't fit the platform owner's vision.
